fix: add support for YouTube Shorts tab on channel pages
All checks were successful
git-sync-with-mirror / git-sync (push) Successful in 13s
CI / test (push) Successful in 56s

- Rewrite channel_ctoken_v5 with correct protobuf field numbers per tab
  (videos=15, shorts=10, streams=14) based on Invidious source
- Replace broken pbj=1 endpoint with youtubei browse API for shorts/streams
- Add shortsLockupViewModel parser to extract video data from new YT format
- Fix channel metadata not loading (get_metadata now uses browse API)
- Fix metadata caching: skip caching when channel_name is absent
- Show actual item count instead of UU playlist count for shorts/streams
- Format view counts with spaced suffixes (7.1 K, 1.2 M, 3 B)
