Module serial_port 

Serial-port setup dialog — the first real configuration sub-dialog.

Lets the user edit the five link parameters of a SerialConfig (baud / data bits / stop bits / parity / flow control) and either apply them to the live session (F2), apply + persist to profile (F10), or cancel. Pushed by crate::menu::RootMenu when the user selects “Serial port setup”.

T12 focuses on the state machine + outcomes; the visual polish (inline edit cursor, per-field validation toasts) arrives in T22.
