fix(frontend): surface upload errors, push ban/lock, route guards (WS8)

Browse Source 
H11: UploadSheet now honors the modal contract — role=dialog/aria-modal +
accessible name, a focus-trap/Escape/focus-restore $effect mirroring
ContextSheet, and inert + pointer-events-none when closed so its controls leave
the tab order and AT tree.

H12: a layout-level $effect toasts each upload-queue item the first time it
transitions to 'error', so a banned/locked/over-quota guest is actually told
why their photo didn't post instead of the composer silently closing.

M10: api.ts now redirects to /join after clearAuth() on a 401 (guarded against
loops on the auth screens), so a 401 no longer strands the user on a dead page.

M11: ban and event-lock are pushed to guests. A new uploadsLocked store is
seeded from /me/context (now exposes uploads_locked) and kept live by
event-closed/opened SSE; the feed shows a banner and the FAB is disabled when
locked. A user-banned SSE event force-logs-out the targeted user.

M19: feed and export pages track a distinct loadError and render an "Erneut
versuchen" retry card instead of collapsing a fetch failure into "empty" /
"not released". Light-mode empty-state text bumped to gray-500 for contrast.
