64 tests covering: auth/setup and the CSRF gate, the "owner adds their
own data, anyone linked can mute it" permission pattern shared across
calendar-select/tasks-source/whiteboard-source, migration correctness
(fresh install, idempotent re-run, expected columns), battery estimate
outlier rejection, calendar_feed's fetch/merge/partial-failure handling,
webdav_client's fetch/list-directory, the whiteboard force-refresh
throttle bypass and browse endpoint, and render-size invariants across
calendar views/orientations.
No DB/HTTP fixtures need Docker, Node, or a real Immich/CalDAV/WebDAV
server -- a fresh temp SQLite file plus a couple of small local HTTP
servers as test doubles cover it all. Table data is wiped and reseeded
between tests rather than relying on SQLAlchemy's transaction-rollback
isolation pattern, which needs a pysqlite event-listener workaround
app/db.py's engine doesn't have and has no reason to gain just for tests.
Wired into .gitea/workflows/server-docker-build.yml as its own job that
build-and-push now depends on, so a failing suite blocks the image push
rather than just running alongside it for show.
