feat(frontend): j/k keyboard navigation for entries; test avatar cached_bytes

App.jsx — j/k handler:
- Fires on keydown when not focused on INPUT/TEXTAREA/SELECT/contenteditable
- Ignores meta/ctrl/alt modifier combos
- Uses DOM order (#entries-body [data-entry-uid]) so expanded child rows
  participate, matching the shift-range selection logic
- Resolves target entry via entryCacheRef → root entries array →
  fetchEntryDetail(..).summary on cache miss
- Scrolls target into view (block: nearest); updates lastAnchorIndexRef
  so subsequent shift-click ranges start from the keyboard-navigated row

archive.rs — cached_bytes_excludes_avatar_blobs test:
- Two tweet entries sharing an avatar blob (100B) and a media blob (900B)
- Asserts refresh_entry_cached_bytes sets cached_bytes = 900 (not 1000)
- Asserts list_root_entries summary: cached_bytes=900, cacheable_bytes=900,
  total_artifact_bytes=1000 — SIZE includes avatar, % cached denominator
  and numerator both exclude it
