feat: migrate files app integration to new API

[susnux]

Since Nextcloud 28 the files app does not support OCA.Files for actions and similar integrations anymore.
Instead we need to use the new files API provided by @nextcloud/files.

So this migrates the files app integration to the new API for Nextcloud 28 and newer (to make it work with current 31 or 32) using current Nextcloud app best practices e.g. using Typescript.

This PR migrates the Nextcloud Maps app's files integration from the legacy OCA.Files API to the modern @nextcloud/files API for compatibility with Nextcloud 28+. The migration introduces TypeScript support and follows current Nextcloud app development best practices.

Key changes:

• Replaces legacy jQuery-based file actions with modern TypeScript implementations
• Migrates to the new @nextcloud/files API for file action registration
