Add tags support for domains with filtering and bulk actions

Introduces a 'tags' field to the domains table and UI, allowing users to organize domains with custom tags. Adds tag input and display to create, edit, bulk-add, and view pages, as well as tag-based filtering and bulk tag management (add/remove) in the domain list. Updates backend validation, controller logic, and migrations to support tags, including a new migration and index for efficient tag searches.
