Jellyfin never consults IsAdministrator when authorizing a library
delete: BaseItem.IsAuthorizedToDelete looks at EnableContentDeletion and
the per-library grant, and only the first user a server creates gets the
former for free. Gating the "Delete from server" entry on the admin bit
therefore offered a destructive action that answers 401 to later
administrators, and hid it from plain users who do hold the grant.
Ask the server per item instead, through the new
MediaDeletionPermissionClient capability: BaseItemDto.CanDelete already
folds the global grant, the per-library grant, and item state such as
missing files or an in-progress recording. The probe runs when a menu
opens on a deletable kind, costs ~0.5 KB, carries a whole-request
deadline because the client's own budget covers connect and receive
separately, and fails closed on anything unknown. Plex keeps its
account-level owner/admin gate; it has no per-item permission on the
wire.

- start binder before navigating from auth, mark isBinding synchronously
- overlap plex.tv resource refresh with optimistic cached-metadata connect,
reconcile tokens/membership in background once it lands
- cached endpoint probe gets a head start on the race instead of serially
blocking it
- defer phase-1 HTTPS upgrade off the splash critical path
- per-server connect progress stream for incremental splash checkmarks
- startup timing instrumentation (bind/fetch/race/connect elapsedMs)
