Introduce sync-bulk-selection.js with per-source processors, header Sync selected controls, and a bottom action bar that stays clear of floating UI widgets.

Sibling to the ListenBrainz Sync tab from Phase 1c.1. Last.fm Radio
playlists already live in the same ``listenbrainz_playlists`` table
as LB ones (``playlist_type='lastfm_radio'``) and run through the
same MB-track discovery worker, so this tab is intentionally thin
— list + render + delegate. Card click hands straight off to the
LB Sync-tab click handler since the downstream modal + state
machine are identical.
- ``webui/index.html``: new ``<button data-tab="lastfm-sync">``
+ tab content container between the LB tab and the existing
Import / Mirrored tabs. Plus a ``<script>`` tag for the new
module.
- ``webui/static/sync-lastfm.js`` (new): ``loadLastfmSyncPlaylists``
hits the existing ``/api/discover/listenbrainz/lastfm-radio``
endpoint, ``renderLastfmSyncPlaylists`` mirrors the LB card
shape with a ``📻`` icon + a ``.lastfm-playlist-card`` brand
class, click handler forwards to
``handleListenBrainzSyncCardClick``.
- ``webui/static/sync-listenbrainz.js``: the shared 500ms refresh
loop now iterates LB + Last.fm cards in one pass and treats
either tab as "active" for liveness. No second loop needed.
- ``webui/static/sync-services.js``: new tab-activation branch in
``initializeSyncPage`` mirrors the LB pattern.
- ``webui/static/style.css``: ``.lastfm-icon`` SVG (Last.fm "as"
logo, red), and ``.lastfm-playlist-card`` joins the unified
card selector group with the Last.fm-red accent
(``rgba(213, 16, 7, ...)``).
- ``web_server.py``: the lastfm-radio endpoint now includes
``track_count`` in its JSPF payload (same fix as the LB
endpoints last commit).
- WHATS_NEW entry added under 2.6.3.
Mirrors created from Last.fm radios participate in the same auto-
trim Phase 1c.1's cascade-delete hook does — when the LB manager
rotates a stale ``lastfm_radio`` row out of its 5-most-recent
window, the matching ``source='lastfm'`` mirror row is removed
along with it. Library files stay on disk.
225 tests across adapter + automation suites still green; this
commit adds no Python paths to test.
