add UBX-MON-VER support and surface device identification in CLI/GUI

Add the Ver message parser and a fixed UbxQuery (was unused and had a
broken semaphore/state bug) to poll MON-VER once on connect. The CLI
prints hw/sw version and extensions; the GUI polls it per receiver,
pre-fills the read-only ID field with a connection counter and
rewrites it from the MOD= extension once the device answers, and
propagates the resolved display name to the Sky and Plot tabs so they
no longer show the stale placeholder ID.
