feat: use Apple Music API for search and update AppleAPI base URL

[Paxsenix0]

• The Apple Music provider now uses the Apple Music API for song search.
• Added automatic JWT token generation (may cause timeouts for users on slow connections).
• Updated the AppleAPI base URL to fetch lyrics.

Please review the changes when you have time! and let me know if anything should be adjusted, I'm afraid this changes might slow down the app.
