1.0.0+kodimov.13: updates don't stop live TV; IPTV Simple restarts only when idle

- After an add-on update the new service found port 57031 still held by the
  old proxy for a moment and moved to a random port; the stream playing kept
  asking 57031 for its manifest and died a minute later (.49, 2026-11-13).
  The proxy now waits up to 10 s for the port, and SO_REUSEADDR /
  allow_reuse_address are set before binding (upstream set them after, so
  they did nothing).
- IPTV Simple is restarted only when nothing plays and no key was pressed
  for 30 s: on .49 a channel opened during a restart failed with an error.
- After start or update, changed instance files (duplicate removed, refresh
  timer) are picked up by the guide reload instead of a restart of their
  own; the service restarts IPTV Simple itself only if that reload didn't
  happen within 10 minutes. 3 restarts after kodimov.12 -> 2.
