fix(filter-builder): id labels resolve at render — refresh keeps names

Refresh showed raw uuids in id-kind value cells (feed/library/
collection/added_by). Two defects, one story:

1. Only ids persist in filter trees; the client's id→label cache dies
   with the page. The quiet re-resolution fetch reused the suggest
   facet, whose rows are MEDIA-CONSTRAINED (INNER JOIN media_items +
   the tree's sibling rules as a constraint) — so an id whose media
   doesn't match got no row and no label. Live repro: "feed in [A,B,C]
   AND title contains Chapter" labeled one feed of three (live-request
   evidence: 200 with total:1). A label is a property of the entity
   row, not of what currently matches.

   Fix: pages that render a tree resolve labels SERVER-SIDE at render
   and embed the map on the mount (data-id-labels) — the collection
   editor (stored tree) and the bookshelf (URL qf). New
   SearchService.FilterTreeLabels reads the entity tables with no
   media join and no tree constraint; scoping rides the request
   identity through the scoped handle (podcast_feeds/collections RLS —
   an invisible id resolves to nothing; pinned), libraries mirror the
   facet's visibility join. A feed with ZERO episodes resolves its
   title — pinned; that case was structurally impossible before.

2. The bookshelf drawer never hydrated at page load at all: the only
   load-time hydrate calls live in the PARENT's x-init
   (initBookshelf), and Alpine initializes parents before nested
   components — builderData() was null there, so hydrateFromForm
   no-oped and a URL-qf refresh left the drawer with an empty seeded
   rule while the grid stayed filtered. The drawer now hydrates in its
   OWN init when the mount carries no data-tree; the init-order
   contract is pinned in vitest (185/185).

The quiet suggest fetch remains only as a fallback for trees the SSR
never saw; embedded labels make it a no-op on refresh. Interactive
menus are untouched (their constrained, count-bearing behavior is
correct for choosing).

Pins: TestRulesPageEmbedsIdLabels (zero-episode feed labels at render,
bookshelf qf library label, hidden library NOT labeled);
filter/episode-tree/search-contract/RLS/playlist container slices
green; contract_pins entry documents the embed contract.
