Music generation for subscribers

Added ability to create music using Yue and ACE Step for subscribers.

Fixed a bug where users who signed in with Tezos were still being asked for their Tezos address on create/edit artist pages.

Added Comedy and Spoken Word genres as well as a number of other musical genres.

Tried to fix dark mode and layout issues on some pages but got nowhere. Taking a month long break from Claude Code. Haven't uploaded new genre songs to radio yet but will do it this week.
