feat(flutter): drift-first MyQuarantine

Final slice of the smooth-loading pass. Adds CachedQuarantineMine
(schema 5, columnar so flag/unflag can do row-level mutation) and
rewires MyQuarantineController to read from drift via watch() + SWR
refresh; flag/unflag write drift first and roll back on REST failure.

Public API (.flag / .unflag / .isHidden) unchanged so existing call
sites (library_screen Hidden tab, TrackActionsSheet) keep working.

Tests updated to match: bypassed-build-via-_StubController approach
no longer makes sense now that state lives in drift, so the suite is
rewritten against NativeDatabase.memory() with the same libsqlite3
skip the sync_controller suite uses on the CI runner.

The Hidden tab now paints from disk on cold open, the list is
queryable offline, and a flag from another device that arrived in
this user's quarantine via SSE-triggered invalidate lands the same
way as a local flag.
