Auto-generate frontend types from OpenApi endpoint

As a developer, I need the up-to-date types for the backend responses so that the typescript compiler finds bugs in my processing of responses.

---

Current situation: We have a types.ts file that was created manually created.

Problem: A lot of types don't match with the response and there is no validation in place, so frontend components fail silently when they expect the manually typed schema.

---

Acceptance criteria:

• front/generated/types.ts is auto-generated on build and develop. It's a superset of the current front/src/types.ts
• All components that process the funkwhale data import front/generated/types.ts to type this data
• front/src/types.ts is deleted
