feat(eventsnap): UX review batch-3 — feed virtualization, a11y/UX fixes, shared primitives

Frontend
- Feed: DOM-windowing via @tanstack/svelte-virtual (new VirtualFeed). The window
  virtualizer keeps the sticky header, pull-to-refresh, infinite-scroll sentinel and
  bottom nav working. List = dynamic measured heights keyed by upload id +
  anchorTo:start so an SSE prepend doesn't jump a scrolled reader; grid = measured
  square rows. Drops the content-visibility band-aid and the old FeedGrid.
  measureElement(null) on row unmount prevents ResizeObserver retention; stable
  option callbacks + guarded setOptions avoid O(n) re-measure on like/comment patches.
- Global: viewport-fit=cover (activates safe-area insets), lang=de, PWA manifest +
  maskable icon + apple-touch metas, prefers-reduced-motion, safe-area-top headers.
- Feed reactivity: like/comment SSE patch the single card in place; upload-processed
  debounced in-place merge; IntersectionObserver leak fixed; shared 60s clock.
- CLS: list cards reserve the skeleton aspect box.
- Destructive actions (promote/demote/unban, gallery release) routed through
  ConfirmSheet (host + admin).
- Export OOM: streamed download via single-use ticket instead of res.blob().
- Shared primitives: IconButton (44px hit area), scrollLock action; UploadSheet a11y.
- Polish: api timeout + non-JSON guard, focus-trap offsetParent fix, pull-to-refresh
  passive:false + guards, diashow keyboard a11y, Toaster assertive errors, dark-mode
  gaps, aria-pressed on like/chip state, CameraCapture mic-on-video + retry,
  ConfirmSheet spinner, upload beforeunload warning, emoji->SVG icons.

Backend
- social.rs: like/comment SSE broadcasts now carry the fresh count so feed clients
  patch one card in place instead of refetching page 1.
- admin.rs / main.rs: supporting changes for the above.

Verified: svelte-check 0 errors, frontend build clean, /feed SSR 200. Runtime feed
scroll-feel validation still owed (documented in FOLLOWUPS.md).

feat(diashow): live slideshow with two-queue policy + pluggable transitions

A fullscreen auto-advancing slideshow any user can start. Design:
docs/CONCEPT_DIASHOW.md.

- lib/diashow/queue.ts: SlideQueue state machine — liveQueue drains first
  (FIFO, seeded by SSE upload-processed), then shuffleQueue (refilled
  from allKnown minus a 5-id ring buffer of recently shown). Pure logic,
  unit-testable.
- lib/diashow/wakelock.ts: Screen Wake Lock wrapper that re-acquires on
  visibility change (the OS drops the lock when the tab hides).
- lib/diashow/transitions/{index,crossfade,kenburns}.ts: registry +
  the v1 transitions. Adding a new animation is one file + one entry —
  the extensibility target from docs/FEATURES §2.9.
- routes/diashow/+page.svelte: fullscreen page, hides bottom nav,
  6 s default dwell (3/6/10 configurable), keyboard shortcuts
  (Escape exits, Space toggles pause), tap-to-reveal overlay with
  pause / dwell / transition / exit. Respects $dataMode to choose
  preview vs. original URL.
