fix(portal): compositor stall detection + filler frames + PipeWire state logging
P0: Detect compositor frame delivery stalls (>100ms no frames) and log
stall/resume events with duration. Rate-limited to 1 warn/sec.
P1: Insert duplicate raw CpuNv12Frame filler during stalls at target fps.
Keeps WebRTC stream smooth (sent_fps 20-40 instead of 3-5 during
compositor pauses). Stops after 2s max stale. WebRTC mode only.
P2: Replace silent _ => {} in PipeWire state_changed callback with
explicit Paused/Streaming/Connecting log messages.
P4: Add PwCtrlEvent::FormatChanged for mid-stream dimension changes.
param_changed detects resolution renegotiation (skips first call).
Logs warning in poll_and_encode; full encoder reinit deferred.
Verified: cargo check 0 errors, 70/70 tests, release build, --stats live.
