fix(livewire): add Locked attributes and consolidate container name validation

- Add #[Locked] to server-set properties on Import component (resourceId,
  resourceType, serverId, resourceUuid, resourceDbType, container) to
  prevent client-side modification via Livewire wire protocol
- Add container name validation in runImport() and restoreFromS3()
  using shared ValidationPatterns::isValidContainerName()
- Scope server lookup to current team via ownedByCurrentTeam()
- Consolidate duplicate container name regex from Import,
  ExecuteContainerCommand, and Terminal into shared
  ValidationPatterns::isValidContainerName() static helper
- Add tests for container name validation, locked attributes, and
  team-scoped server lookup
