Better-Auth generates nanoid-style text IDs (e.g. pGud2ln2WAFHC0KYjBVKR4Rc7mM8OcTI), but the users table used PostgreSQL uuid type, causing registration failures: ERROR: invalid input syntax for type uuid: "pGud2ln2WAFHC0KYjBVKR4Rc7mM8OcTI" Changes: - User.id: removed UUIDPrimaryKeyMixin, use explicit text PK - UserStoreAccount.user_id: Mapped[uuid.UUID] -> Mapped[str] - Purchase.user_id: Mapped[uuid.UUID] -> Mapped[str] - UserResponse schema: id field from UUID -> str - New Alembic migration 004_fix_user_id_text: drops FKs, alters column types, re-adds FKs (using id::text cast) Co-Authored-By: Paperclip <noreply@paperclip.ing>
