Report mute/hardware status correctly, add Local Mic Mute, fix stale talking indicator

- Mute/deafen status now goes out through clientupdate instead of
  clientedit, which silently rejected client_input_muted/output_muted
  since they are runtime status, not editable client properties.
- Publish client_input_hardware so other clients see "Microphone
  Disabled" instead of silence while another tab holds the capture
  device; track input/output hardware flags for other clients too,
  and show a distinct grey "disabled" icon instead of reusing the red
  "muted" one for both the tree and the info panel.
- Implement TS3's Enable/Disable/Toggle Local Mic Mute hotkeys: they
  silence capture like a real mute, but never touch the published
  mute status or play a sound.
- A speaker's "talking" indicator only ever cleared when its
  zero-length end-of-burst voice packet arrived; if that one UDP
  packet was lost, the indicator stuck until their next burst. Add a
  watchdog that clears it after 200ms of silence from that speaker
  regardless.
