Reifen/Version/Wartungsplan: erste Runde des Sammel-Feedbacks behoben

- Archiv-Knopf jetzt in Zeile mit "Montiert" (stale margin-top entfernt),
  bekommt einen sichtbaren Hintergrund
- companion-app: Wechseltermin-Datumsfeld (appearance-Reset gegen
  natives Safari-Chrome, Breite auf Inhalt geschrumpft)
- Mein Audi/Reifen-Box: "montiert: Sommerräder" links statt Marke/Modell,
  "offen" durch "-" ersetzt
- "Servicebuch" ueberall in "Wartungsplan" umbenannt (nur Anzeigetext,
  beide Codebasen)
- Version-Kachel: tote Fahrzeugdaten-/Position-/Dashboard-Zeilen entfernt
  (inkl. der nie aktualisierten CONFIG.version-Konstante)

Version 2026.8.28.1, live im Testcontainer verifiziert.

+## AB. First round of a large owner batch: Reifen/Version/Wartungsplan fixes (2026.8.28.1)
+
+Owner sent 12 items in one message. Worked through the quick, well-specified ones first; the two larger
+ones (combined export/import popup, Setup-menu sensor field redesign) are being scoped with the owner before
+implementation - see the open items this creates below.
+
+- **Archiv-Knopf nicht in Zeile mit "Montiert"** (Reifen-Seite, panel only - no companion-app equivalent):
+  root cause was `.montiert`'s own `margin-top:var(--sp-4)` (added 2026-08-16 round eight, when the pill sat
+  alone under the headline block) - once the archive icon button joined it on the same flex row (section R),
+  that leftover margin threw off `align-items:center`'s vertical centering between the two children, even
+  though both were genuinely siblings in the same row. Moved the spacing to the wrapping row div instead of
+  one child. Verified live: both centers compute to the identical `584.08px` Y-coordinate.
+- **Archiv-Icon soll ein Knopf mit Hintergrund sein**: new `.archivbtn` class (panel), permanent
+  `background: var(--tile-2)` instead of the generic `.iconbtn`'s hover/active-only background.
+- **companion-app: Wechseltermin-Datumsfeld sah aus wie ein gestreckter Kreis statt einer Box**: root cause
+  is the standard cross-browser gap - `input[type="date"]` needs an explicit `appearance:none` reset or
+  Safari/WKWebView (this app's iOS shell) keeps its own heavily-rounded native chrome regardless of author
+  CSS on `background`/`border`/`border-radius`. Neither `.dm-eingabe` nor the shared `@audi-dash/ui` `Feld`
+  component reset it. Fixed locally in `companion-app/src/stile/screens.css` (not in the shared design-system
+  package - no other field type shows this, scoped to `input[type="date"].dm-eingabe` only) with
+  `-webkit-appearance:none`/`appearance:none` plus `width:fit-content` (owner's explicit ask: shrink to the
+  actual date text instead of the shared `Feld`'s `min-width:132px`). **Not live-verified** - no running
+  companion-app session with backend auth this round; verified via `tsc --noEmit` and the full suite only,
+  same limitation as several other companion-app-only changes this session.
+- **Mein Audi/Reifen-Box restructured**: was `Reifen · Sommer montiert` as the tile header, then
+  `<dt>Continental SportContact</dt><dd>275/30 R20 97Y XL</dd>` as the first row. Header simplified to just
+  "Reifen"; the row's left side now reads `montiert: Sommerräder` (owner's exact wording, `${r.aktiv}räder`)
+  instead of the brand/model, keeping the size (`275/30 R20 97Y XL`) as the right-hand value, per the owner's
+  explicit "montiert... shall be on the left side". companion-app's equivalent "Mein Audi" tile
+  (`MeinAudi.tsx`) is structurally a single-line `NaviKachel` (`${aktiv} · ${km} km`), not the panel's
+  multi-row `.rows` list - it never had "Sommer montiert" or brand/model text to begin with, so nothing to
+  port here (documented structural difference, not a skipped fix).
+- **"offen" caption removed from the Wechseltermin row**: `vereinbart ? "vereinbart" : "offen"` → `... : "–"`
+  - owner: "the '-' is sufficient". Same structural note as above - companion-app's tile has no equivalent
+  caption to change.
+- **"Servicebuch" renamed to "Wartungsplan" everywhere it's user-visible**, both codebases - tile/page
+  headings, empty-state text, confirm-delete dialogs, CSV export button label, the "Mein Audi" Service
+  NaviKachel's summary text. Deliberately NOT renamed: the `ServicebuchEintrag` TS type, the `Servicebuch()`
+  component/function names (panel and companion-app), the `sbuch` route key, and every code comment - same
+  precedent as the 2026-08-19 "Zusammen"→"Summe" rename (display-label fix, not a data-model rename).
+- **"Version" tile cleaned up**: removed the "Fahrzeugdaten"/"Position" rows (both hardcoded to the literal
+  string "FMM003", carried no live information) and the "Dashboard" row, whose value came from `CONFIG.version`
+  - a frontend constant hardcoded to `"1.0"` at `profilZuConfig()` (confirmed via grep: no other reader),
+  never updated since. Removed that dead constant along with its row rather than leaving an orphan. Only
+  "Installiert" (the real `APP_VERSION` from the backend) remains.
+
+Verified: `node --check` clean on the panel, `tsc --noEmit` clean and full suite green (146/146) on
+companion-app. Manifest bumped to `2026.8.28.1` (new day, per this project's `YYYY.M.D.N` scheme - the prior
+session's work had reached `.27.22`). `audi_ha_test` restarted, confirmed clean via log
+(`Audi Dashboard 2026.8.28.1 eingerichtet`). Live-verified via the panel's own shadow DOM: Reifen tile shows
+`montiert: Sommerräder | 275/30 R20 97Y XL` and `15.10.2026 | –`; Version tile shows only "Installiert"; the
+Archiv button and "Montiert" share one Y-center exactly, with a visible background disc behind the icon
+(screenshot taken).
+
+**Open, not yet started - scoped with the owner before implementation:**
+- **Item 8 (informational, answered in chat, not yet acted on)**: both the live path
+  (`tankerkennung.py`→`ablage.distanz_seit_letzter_tankung()`) and the import path
+  (`historienimport.py`'s `_distanz_zum_vorherigen()`) compute "distance since last refuel" as an odometer
+  delta (current/refuel `KM_SENSOR` reading minus the previous refuel's own recorded `odometer_km`) - a
+  derived calculation, not read from any vehicle sensor. Owner pointed out a real FMM003 sensor,
+  `sensor.testzone_fmm003_calculated_distance_covered_after_the_latest_refueling` (device-side, presumably
+  more accurate/authoritative than our own subtraction), that reports this directly and "can be used instead
+  of the calculation" - not yet wired in, would mirror the `TANK_LITER_SENSOR` precedent (section Q): new
+  optional sensor role, preferred over the calculation when mapped, calculation stays as the fallback when
+  unmapped. Owner to confirm before this is built.
+- **Item 9**: combine the "Fahrzeugprofil" tile (`data-profil="export"`/`"import"`, JSON) and "Daten ausgeben"
+  tile (`data-csv="fahrten"`/`"tanken"`/`"service"`, CSV export only, no import) into one area with two
+  buttons - "Datensatz sichern" opening a popup with 4 individual export actions (Fahrzeugprofil,
+  Fahrten/Tankvorgänge/Wartungsplan as CSV), "Datensatz laden" the same 4 in reverse. The pre-existing,
+  separate "Backup" tile (`data-backup="jetzt"`/`"export"`/`"import"`, a combined profil+fahrten+tank JSON
+  bundle plus the scheduled-backup mechanism) was NOT named by the owner and stays untouched. Three of the
+  four export actions and one of the four import actions already exist and just need moving into the new
+  popup; CSV **import** for Fahrten/Tankvorgänge/Wartungsplan does not exist anywhere yet and needs new
+  backend parsing (inverse of the existing CSV export format: `;`-delimited, de-DE number format).
+- **Item 11**: Setup-Menü sensor role fields - replace the current description text under each field's
+  headline (e.g. "on = Fahrt läuft", "Optional, vom CAN...") with the live sensor's current output value and
+  unit inline next to the headline (`[on/off]`, `[%]`, `[l]`, `[km]`...), and show the matched entity's ID
+  suffix (the part after `fmm003_...`) as "the expected sensor" - not yet investigated in the code
+  (`entitaeten.py`'s `FELDER` catalog / the Setup popup's row-rendering in the panel).
