Unauthorized Dialog

Overview

Displays when the client dispatches the brewski:unauthorized event after a 401 so users understand their session expired.
Locks the rest of the UI until the dialog is dismissed or the user re-authenticates, preventing partially authorized actions.
Pre-fills the known e-mail address and blocks edits so users only supply a password for re-entry.

Cancel closes the dialog and keeps the user signed out; the app stays in a read-only state until a fresh login occurs.
Submitting triggers authService.login with the pre-filled e-mail and entered password; success updates the auth context and hides the dialog.
Validation surfaces translated errors for missing credentials, invalid password, or unexpected failures.

The center branding now uses /images/brewski-clear.png so the sign-out prompt matches the current marketing mark.
The brand image is constrained to a 48 px height (h-12 w-auto) and carries 44 px bottom margin to respect modal spacing guidance for Admin dialogs.
