Delete SQLite sibling files together with the database, clean up orphaned journal files before creating a new database, and model the result of opening the on-disk cache as an OnDiskCacheOutcome (opened, recovered, or failed) carrying a typed OnDiskCacheFailure. bootstrap() reports failures (each kind from its own call site so wpAssertionFailure's file/line-based analytics identity and suppression stay per-kind) and falls back to the in-memory cache, while the pure worker lets unit tests drive the recovery path without tripping assertionFailure in Debug. A failure to remove a sibling next to a fresh database is itself a corruption vector, so it fails rather than reopening against a stale journal.
Per-client cache instances each opened a connection to the same app.sqlite and re-ran migrations with BEGIN EXCLUSIVE, so concurrent bootstraps could fail with SQLITE_BUSY and delete a database other connections still had open (Sentry JETPACK-IOS-1KCJ). A process-wide shared instance bootstraps once, matching the Android app's singleton cache. Test helpers that built a service from bootstrap() now use the shared instance since bootstrap() is private.
Removing an account or site left its cached API data in app.sqlite, so a later re-add could read stale entries. Delete the cached data for each affected site during removal. The cleanup runs on the process-wide WordPressApiCache.shared instance rather than opening a separate connection to the database. A second connection would reintroduce the bootstrap contention this branch eliminates and would not notify the shared instance's update listeners, since SQLite update hooks fire only for writes on their own connection.

Description
The main changes is in
WordPressApiCache.Every
WordPressClientopened its ownWordPressApiCacheagainst the sameapp.sqliteand re-ran migrations. This PR makes the cache a single process-wide instance and to avoid unnecessary migration runs, which matches the Android app's singleton cache.The main changes:
OnDiskCacheOutcome(opened, recovered, or failed) carrying a typed failure.WordPressApiCache.sharedinstead of bootstrapping per client, so the database is opened and migrated once per process.
