refactor(cctv): isolate calibration handles and stop idle poll frames

Move native gizmo entities and input into an owned renderer. Restore the
captured camera-input flag, handle cancellation and duplicate presses, and
reject foreign handle identities. Preserve native geometry and picking.

Avoid no-op sync-chip mutations and let unchanged CCTV polls complete
without publishing scene changes. Keep health/UI polling and real geometry,
auto-hop and media updates. Extend browser idle samples across two polls.

Validated full Node24 unit/allocation, boundaries, scoped format, production,
panel and QA builds; native legacy parity, real media/GPU picks on dev and
preview, engine contracts and production shell. Retain failed evidence.
