Input: PadRIO -- play without the pod (L4CONTROLS=PAD), Workstream A.1

Browse Source 
Ported from RP412: RIOBase split out of the serial RIO (L4RIO.h),
rioPointer is RIOBase* (L4CTRL.h), PAD token -> new PadRIO() speaking
the RIO surface from an XInput pad + keyboard (L4PADRIO/L4PADBINDINGS,
vRIO bindings.txt grammar, hot-plug), KeyLight RGB mirror TU
(BT412KEYLIGHT, /std:c++17 per-file).

BT-side fixes PadRIO forced into the open:
- Both keyboard input bridges (mech4.cpp, mechmppr.cpp BT_KEY_BRIDGE)
  stand down when a RIO device exists -- they overwrote the engine
  controls push every frame. M/X conveniences stay live.
- Mapper attribute chain OFF BY ONE (latent real-pod bug): the DOS
  chain below MechControlsMapper carried two base attributes, WinTesla
  carries one, and AttributeIndexSet::Find is positional -- the .CTL
  stick mapping wrote throttlePosition. Pad slot + binary-locked enum;
  gotcha ledgered (reconstruction-gotchas #11).

Verified: PAD throttle lever ramps + sticks, stick turns with the
authentic speed-vs-turn clamp (61.5 -> 22.0 u/s), mech drives; keyboard
fallback intact (BT_FORCE_THROTTLE harness). New diags: BT_CTRLMAP_LOG,
BT_STICK_LOG. (Phase 2 of docs/BT412-ROADMAP.md)
