feat(livewire): add selectedActions parameter and error handling to delete methods

- Add `$selectedActions = []` parameter to delete/remove methods in multiple
  Livewire components to support optional deletion actions
- Return error message string when password verification fails instead of
  silent return
- Return `true` on successful deletion to indicate completion
- Handle selectedActions to set component properties for cascading deletions
  (delete_volumes, delete_networks, delete_configurations, docker_cleanup)
- Add test coverage for Danger component delete functionality with password
  validation and selected actions handling
