Prepared-statement writes dispatched via drizzle's `.execute()` on the
better-sqlite3 driver return a promise and defer the write to a microtask.
Inside a synchronous `db.transaction(() => ...)` callback (which cannot
await), the transaction commits before that promise settles, so the write
is a silent no-op — no error, no rows changed.
This bit `reorderGlobalFavorites`: the custom favorites order never
persisted for the per-playlist ("This playlist") Xtream scope, which relies
solely on the `favorites.position` column. The global ("All playlists")
scope masked the bug because it also persists an order to the `appState`
`global-favorites-channel-order-v1` key and re-applies it on read.
`removeRecentItemsBatch` had the same latent bug — batch "clear recent
items" silently did nothing.
Switch both writers to synchronous `.run()`. Add regression coverage that
asserts `.run()` (not `.execute()`) is used and would fail on the old
behavior, and document the gotcha in the DB worker architecture doc.
Verified over CDP against a live Electron instance: reorder writes
positions 0..N, and the order survives navigation and a full reload.
Fixes #1137
