fix: recover gracefully from stale sessions causing repeated 401s

The SPA's session check (/api/auth/session) is cached indefinitely by
react-query (staleTime: Infinity, no refetch on focus/interval), so once a
protected page mounts successfully, the app never re-verifies auth. If the
server-side session later becomes invalid (server restart with in-memory
sessions, cookie/session expiry, etc.), every subsequent API call
(pages, scheduled-posts, audio-tracks, media, media/upload, ...) starts
failing with 401 in a loop with no way for the user to recover short of a
manual page reload.

Add a shared handleUnauthorized() in queryClient.ts that redirects to
/login on any non-auth API 401, wired into both the shared fetch helpers
(apiRequest/getQueryFn) and the raw fetch() calls used for file uploads
and Remotion rendering, which also lacked this recovery path. Also add the
missing credentials: "include" to those raw fetch() calls for consistency
with the rest of the app's API requests.
