feat(v3 library): A–Z fast-scroll jump rail on the Songs grid (#634)
* feat(v3 library): A–Z fast-scroll jump rail on the Songs grid

Adds a vertical letter rail (Plex/Radarr/iOS-contacts pattern) pinned to the
right edge next to the scrollbar so you can jump the library to a starting
letter — tap, drag-to-scrub with a live letter bubble, or arrow-key between
letters. The classic (v2) tree already had letter selection; this brings the
new v3 grid to parity (it was the gap behind the "alphabetical scroll
selection next to the scrollbar" idea).

It shows ONLY for the grid view + alphabetical (artist/title) sorts, and only
offers letters present in the current sort AND filter set, so a tap always
lands on a real card (absent letters are dimmed + non-interactive). The grid
is forward-only, server-paged infinite scroll with no virtualization, so a
jump pages through to the target card then scrolls to it; a token guards
overlapping jumps (drag) so the newest wins. A keyset-seek + virtualized
window is the scaling follow-up for very large libraries.

Backend: /api/library/stats gains an optional `sort` param and an additive
`sort_letters` map — songs-per-first-letter of the ACTIVE sort column (artist
or title), filter-synced — so the rail's present-letters match the grid's real
order. The legacy `letters` (distinct-artist) field is unchanged, so the
dashboard + classic tree are unaffected. `sort` is dropped for providers whose
query_stats predates it (existing kwarg-filter), so third-party library
providers keep working (rail simply falls back / hides).

Frontend: static/v3/songs.js (refreshRail / jumpToLetter / pointer-drag +
keyboard, cards tagged data-letter), static/v3/v3.css (.v3-azrail + bubble).

Tests: tests/test_library_filters.py (sort_letters artist/title, song-vs-
distinct-artist counting), tests/test_library_providers.py (sort forwarded),
tests/js/v3_az_rail.test.js (gating, data-letter, load-through, drag/keys).

* fix(v3 library): harden A–Z jump rail (review P2/P3)

Addresses the PR #634 review findings (manual + Codex):

P2 correctness
- refreshRail prefers the active-sort `sort_letters`; falls back to the
  artist-based `letters` only on an artist sort, and hides the rail on a
  title sort when a legacy provider returns none (was mislabeling letters).
- reload() bumps `_jumpToken` so an in-flight letter jump can't scroll a
  grid that's being rebuilt from page 0.
- songBucket no longer trims, matching the server SQL + grid ORDER BY raw
  first-char bucketing (a leading-space title now buckets under '#' on both
  sides).

P3 polish
- Paging guard is total-derived (ceil(total/PAGE_SIZE)+2) instead of a
  magic 4000, keeping large libraries reachable while still bounded.
- Roving tabindex: only the first present letter is tabbable; arrow keys
  move it. Removes up to 27 page tab stops.
- `sort_letters` is computed only when the caller opts in
  (want_sort_letters / route `sort_letters=1`); the dashboard + v2 tree
  skip the extra GROUP BY. Added sort + want_sort_letters to the optional
  provider-kwargs so non-introspectable legacy providers drop them.
- _railToken supersedes stale refreshRail responses; hide the rail when no
  letters are present instead of rendering disabled buttons.

Tests updated accordingly (v3_az_rail.test.js, test_library_filters.py).
