chore: final cleanup — dead link, security status, showTitle, drop subscriptions

1. CompleteStep: /apps → / ("Workbench" instead of dead "Alle Apps")
2. pnpm lockfile synced after @mana/subscriptions removal
3. Security header panel: status dots for Passkey/2FA/Sessions count
4. GeneralSection: inline settings rows replace GlobalSettingsSection
   wrapper — no more title="" hack or double-card nesting
5. shared-auth-ui: showTitle prop on PasskeyManager, SessionManager,
   TwoFactorSetup, AuditLog; SecuritySection passes showTitle={false}
6. Drop @mana/subscriptions from sources.css + package.json
