feat(modbus): wire Family / MelsecSubFamily / DisableFC23, and the form's timing keys

U1: a tag's addressString (Modicon / mnemonic / DL205 V-memory / MELSEC
D-X-Y grammar) now resolves through ModbusAddressParser with the DRIVER's
Family and MelsecSubFamily at every initialize and is authoritative; the
family-unaware gates (deploy Inspect, AdminUI parse consult) accept what
some family resolves. The tag editor gets an address-text field that
resolves with the owning driver's family and persists both the string and
the resolved region/offset/type fields; a hand edit drops the string.
DisableFC23 now gates FC23: by default a 2..121-register holding write is
one FC23 write + read-back (a unit answering exception 01, or failing FC23 at
the transport, moves to FC16 for the rest of the generation); RTU framing
deframes the FC23 reply. Live-checked: the pymodbus fixture implements FC23.
Also: the AdminUI driver form serialises ModbusDriverOptions (TimeSpan
strings), which the factory DTO never read - every timing field on the form
was dead. The DTO now accepts both shapes (*Ms keys win).
