Merge pull request 'rc(v05.04.00): login notifications, help footer, login logo, checksum fix' (#210) from rc/05.04.00 into main

When a user signs in, sends notifications with username, IP address,
user agent, and timestamp. Notifications go through:
- Email to the user's registered address
- ntfy push to the configured topic

Enabled by default, configurable via app.ini:
  [login_notification]
  ENABLED = true

The notification fires asynchronously (goroutine) so it doesn't
block the login redirect. Hooks into handleSignInFull which is the
single choke point for all auth methods (password, 2FA, OAuth).
