feat(mesh-ui): region-recommended RNode plan applies from the setup modal too

The device-detected modal's region selector now drives real RNode
settings instead of a "managed by the daemon config" shrug: choosing a
region shows its concrete plan (frequency/bw/SF/CR/power) and Apply &
Connect writes it through mesh.rnode-config-apply — the same
radio-confirmed round-trip as the Device panel, best-effort so a plan
failure never aborts the connect. RNODE_REGION_PLANS moves to
utils/loraRegions (single source shared by panel + modal).
