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>

"""Fix users.id UUID->text type mismatch for Better-Auth compatibility.

|
|
Better-Auth generates nanoid-style text IDs (e.g. pGud2ln2WAFHC0KYjBVKR4Rc7mM8OcTI),
|
|
but the users table was using PostgreSQL uuid type. When Better-Auth tries to INSERT
|
|
a new user, Postgres throws:
|
|
ERROR: invalid input syntax for type uuid: "pGud2ln2WAFHC0KYjBVKR4Rc7mM8OcTI"
|
|
|
|
The sessions, accounts, and verifications tables already use text IDs — only users,
|
|
user_store_accounts.user_id, and purchases.user_id needed fixing.
