Index transcripts into library search (FTS), both UIs

Browse source 
The 🔍 library search now matches spoken words, not just titles /
channels / descriptions.

- database.rs: add a `transcript` column to the `video_search` FTS5 index.
  Fresh DBs get it directly; existing ones are migrated (FTS5 has no ADD
  COLUMN, so the table is recreated and search_meta cleared to force a
  one-time reindex). `sync_search_index` reads each video's first subtitle
  (mtime-gated like the description), flattens it via the shared `vtt`
  parser (`transcript_text`, capped at 256 KB), and indexes it. Search
  snippets now use column -1 so the excerpt comes from whichever column
  matched (description or transcript).
- library.rs: `build_search_entries` passes the first subtitle path.
- Both UIs: search copy updated to mention transcripts.

Tests: a unit test (a word only in the .vtt is found), a migration test
(seed an old 5-column index + stale meta, open, confirm the recreated
index indexes transcript text), and the search integration test now seeds
a subtitle and asserts a spoken-only word hits. Also bumped the test
server's startup budget so the ffmpeg-heavy dedup test can't starve a
sibling server into a flaky timeout. 120 tests pass.
