feat: move Apps from admin to main tab bar with container config

- Apps tab visible to OPERATOR+ (hidden for VIEWER), scoped by
  sidebar app selection and environment filter
- List view: DataTable with name, environment, updated, created columns
- Detail view: deployments across all envs, version upload with
  per-env deploy target, container config form (resources, ports,
  custom env vars) with explicit Save
- Memory reserve field disabled for non-production environments
  with info hint
- Admin sidebar sorted alphabetically, Applications entry removed
- Old admin AppsPage deleted
