Beatport: switch search to v4 catalog API (credit: @Simon-Zwa, upstream PR Marekkon5#523) (#1)

* Fix Beatport search after __NEXT_DATA__ removal

Beatport no longer exposes __NEXT_DATA__ on search pages, causing search failures.

Updated Beatport search to use the v4 catalog API endpoint instead of scraping the website.

Adjusted deserialization to support the new API response format (tracks array).

* Update README with temporary Beatport fix note

Added a note about a temporary Beatport fix for May 2026.
