fix(usage): close the QA findings on opt-in product usage

A QA exploration of this branch against an isolated rig — own stub
collector, SQLite and PostgreSQL — turned up one dead end and a set of
signals and controls that did not hold up. This closes all of them.

Rotating JWT_SECRET, the documented response to a suspected compromise,
made the signing key unreadable. That was already named and documented,
but it left no way out: the delete packet can never be signed, so the
row stays deletion_pending forever, and enable() refuses because it is
not `disabled`. An operator who rotated precisely because the secret was
compromised cannot restore it, so the feature was bricked with no
control left. POST /usage/abandon is offered only in that state; it
drops the local identity and records the receipt as
`collector-unconfirmed` rather than claiming a deletion that did not
happen.

Every failed delivery was retried on the next admin request, and
/activity is open to any authenticated admin while the settings ticker
fires it every five minutes per open tab — 30 activity calls against a
rejecting collector produced 30 outbound requests. Migration 206 adds
attempts/next_attempt_at and the unattended sender honours the gate;
Retry and opt-out still send immediately, and the tab names the time of
the next automatic attempt.

Feedback, votes and portal sessions now share an installation-wide
budget of 30/hour. They are the only endpoints whose effect is outbound
traffic carrying operator-written free text, and the general limiter
skips authenticated requests by design. Reading status and withdrawing
stay unthrottled.

gallery_image_protection was true on a bare install with no galleries:
PicPeak ships default_protection_level='standard' and
enable_devtools_protection=true, so it reported fleet-wide 100% and
could never separate a decision from an untouched default. It now reads
only what deviates from the shipped defaults, and the devtools flag is
not read at all — being on by default, its only informative state is
off, which is the opposite of what the key claims.

Also:
- the export receipt counted every packet and called the total "usage
  reports"; reports and participant operations are now counted and named
  separately
- GET /usage/preview no longer persists the custom_css marker, so the
  transparency view stops changing what will be sent
- the feedback route requires every field the packet schema requires,
  so an API caller gets the missing field named instead of a bare
  INVALID_PACKET from inside signing
- the German strings for this feature use "Sie" throughout, matching the
  rest of the admin UI; the ignore hint says what ignoring will do
  rather than stating it as already true
- the consent dialog returns focus to the control that opened it
- the long buttons wrap instead of running off a 390px viewport
- a deletion receipt is labelled as belonging to an earlier
  participation while a new one is active

Regression tests cover each of these, including the delete packet's
reuse of the last accepted sequence, which was an unwritten assumption
about the collector rather than a defect.
