AdminUserRow shows username + admin/auto-approve badges; tap opens
AdminUserEditSheet bottom sheet.
Edit sheet: SwitchListTile pair for is_admin and auto_approve_requests
(both surface server errors via SnackBar, including the last-admin
guard). Reset password takes a typed-input dialog (>=8 chars enforced
client-side; admin supplies the new password). Delete routes through
TypedConfirmSheet ("DELETE") and pops the sheet on success.
