chore(stable): release 3.45.12 (#955)

* fix(security): redact gallery share tokens from analytics page-view tracking (GHSA-7m6c)

* fix(security): codex round-1 — actually disable raw auto-tracking (GHSA-7m6c)

The previous patch was inert: App.tsx passed autoTrack:true (so Umami's
data-auto-track=false was never set) and the sanitized trackPageView had no
caller (useAnalytics sits outside <Router>), so the raw token URL still hit
the collector.

- Umami: drop autoTrack:true → data-auto-track=false; page views now come
  from a sanitized manual tracker.
- Rybbit: its initial-load auto pageview can't be intercepted client-side, so
  use native data-mask-patterns=['/gallery/**'] to strip the token on every
  auto-tracked view; skip manual tracking for it to avoid double counting.
- Mount <AnalyticsRouteTracker/> INSIDE <Router> so manual tracking runs.

+# e.g. 3.45.8 AND 3.45.9 on the same day). This workflow merges the open
+# stable release PR once a day, so a day of N bugfixes ships as ONE version
+# with all N changelog entries — and one Docker build instead of N.
+#
+# - schedule only fires from the default branch (main); the stable copy of
+#   this file is inert and exists to keep the branches in sync.
+# - Need a release NOW? Run this via workflow_dispatch, or merge the
+#   release PR by hand — the schedule is a default, not a gate.
+# - Approval/merge mechanics mirror the old inline step (#719): approve as
+#   github-actions[bot] (GITHUB_TOKEN, a valid distinct reviewer), enable
+#   auto-merge as the PAT so the merge attributes to a real identity and
+#   triggers the tag-cutting run. --auto waits for green checks.
