feat(feed): remove deprecated feed types and make unknown-type handling consistent

Remove the feed types deprecated in 2.x — SparkleIOFeedType,
EventDatabaseApiFeedType and KobaFeedType — for the 3.0.0 release.

feed_source.feed_type stores the FQCN as a plain string (not an FK), so
removing a class leaves orphaned rows that FeedService::getFeedType() can no
longer resolve. Make that handling consistent across the API:

- Reads degrade, never 500: FeedSourceProvider::toOutput() catches
  UnknownFeedTypeException and exposes no secrets, so feed sources (and feeds
  embedding them, item and collection) stay listable and removable. The feed
  data endpoint already returns an empty result.
- Writes reject: creating/updating a feed source with an unknown feed type maps
  UnknownFeedTypeException to HTTP 422 (was an opaque 500) via exception_to_status.

Tooling for cleaning up referencing rows:

- DeprecatedFeedSourceFinder + app:feed:remove-deprecated-feed-sources (dry-run
  report; --force removes the feed sources, their feeds and the bound slides,
  cascading to PlaylistSlide), covering all tenants.
- app:update prints a notice when deprecated feed sources remain.

Also remove the backend/frontend references (admin feed-type selector, the v1
event-database config component and its translation), switch test fixtures to
EventDatabaseApiV2FeedType, regenerate the PHPStan baseline, and document the
upgrade step in UPGRADE.md / CHANGELOG.md.

+  Migrate event database feeds to `EventDatabaseApiV2FeedType`. See `UPGRADE.md`.

+
+The feed types `SparkleIOFeedType`, `EventDatabaseApiFeedType` and `KobaFeedType` were deprecated in
+2.x and **removed in 3.0**. Unknown feed types are now handled consistently: **reads degrade, writes are
+rejected.** Feed sources that still reference a removed type keep loading (item and collection reads
+return them with no exposed secrets, and feed data endpoints return empty) but can no longer fetch data;
+creating or updating a feed source with such a type returns HTTP 422. `app:update` prints a notice when
+any such feed sources exist.
+
+Review them, then remove them together with their feeds and slides:

+```shell
+# Report feed sources referencing a removed feed type (no changes made).
+docker compose exec phpfpm bin/console app:feed:remove-deprecated-feed-sources
+
+# Remove them, their feeds and the slides bound to those feeds.
+docker compose exec phpfpm bin/console app:feed:remove-deprecated-feed-sources --force
+```
+
+Event database feeds should be recreated using `EventDatabaseApiV2FeedType`.
