fix(client/gamepad): honor an explicit controller type — the per-pad arrival was re-declaring the physical pad

The "Controller type" setting reached the Hello and stopped there. Every pad then
opened with a GamepadArrival carrying its DETECTED kind, and the host builds each
virtual device from that arrival — the session default is only the fallback for a
pad that never declares one. So "emulate my DualSense as a DualShock 4" put a
DualSense on the host the instant the controller connected, and no amount of
reconnecting helped. Apple and the native clients both; Android already applied
the setting per pad.

The setting now rides the declaration too: explicit wins for every slot, Automatic
keeps per-pad detection so a mixed session stays honest. The physical kind still
drives the LOCAL feedback paths — a DualSense emulated as a DualShock 4 keeps its
lightbar and adaptive triggers, and a Deck keeps its rumble keep-alive.

Regressed in 97c67b26 / 76be4c3e (multi-controller support); ships in 0.19.x.
