syncdoom: fix RTT stale-reject ratchet + audio/frame telemetry

- RTT: pass stale_reject=0 to termgfx_rtt_sample. That filter dropped any DSR
  round-trip below EMA/3 to reject "absurdly low" late replies -- but it created
  a one-way ratchet: once a slow JXL frame spiked the smoothed RTT, every good
  low sample was then below EMA/3 and discarded, so it could never recover
  (observed latched ~725ms on a ~20ms LAN, which also forced the synthetic
  turn / "evdev/syn"). Reclaimed-frame replies are already dropped above via
  g_dsr_stale, so the filter guarded nothing here. Matches SyncDuke, which runs
  the same shared function with stale_reject=0 and tracks the true link.
- Telemetry: the music line now splits render=<transcode ms> xfer=<encode+cache+
  upload ms> so a load stall's cause is unambiguous; a frame-stall watchdog logs
  when emit_frame runs long (>500ms, a slow encode); and dlog gains a [+ms]
  prefix (the BBS log only stamps to the second).
