Adds a "API Tokens" settings page so an authenticated user can create and
revoke Sanctum personal access tokens for the new authenticated write
endpoints — using the official Sanctum API ($user->createToken() / tokens()).
- New Volt component settings/api-tokens (create token, one-time plain-text
reveal with copy-to-clipboard, list + revoke own tokens).
- Registered route settings.api-tokens (country-prefixed, auth group) and
added a nav entry in the settings layout.
- SEO definition for the new page.
- Pest feature tests (create/reveal-once, validation, revoke, ownership
scoping) and a Pest browser screenshot test.
- Updated settings route links to include `country` parameter dynamically resolved from session.
- Improved relational queries by adding `city.country` to meetups map and `coursesEvents.course` to lecturers data.
