"""Connection helper for the CMMC USB check-in/out database.

|
|
|
Credentials are pulled from app config (env-backed, see Config.CMMC_USB_DB_*),
|
|
never hardcoded. Used by the USB plugin to track device check-in/out against a
|
|
separate MySQL database (cmmc_usb), mirroring the read-only employee-directory
|
|
pattern in employee_db.py. Unlike the employee DB this one is read-write, so
|
|
callers commit their own writes and close the connection in a finally block.
