- Modified the user account creation process to automatically credit new
accounts with 1,000,000 satoshis upon creation.
- Updated the `create_user_account_no_ckeck` function to include error
handling and logging for the credit operation.
- Enhanced tests to verify the balance for newly registered users,
ensuring the correct credit amount is applied.
- Documented affected account creation paths and testing instructions in
the new `AUTO_CREDIT_CHANGES.md` file.
fix: pass db connection to update_wallet_balance to prevent SQLite deadlock
The auto-credit feature was causing a deadlock on SQLite because
update_wallet_balance was opening a new database connection while
already inside a transaction. By passing conn=conn, we reuse the
existing connection and avoid the deadlock.
