1.0.0+kodimov.14: guide reload no longer skipped while the remote is in use; remove empty instances

- .190 on 2026-11-13: the box came on with an old epg.xml, Kodi stored it
  (no current programmes for 124 channels) and doesn't ask again for up to
  an hour. KodiMov+ wrote a new guide two minutes later, but the reload
  waited for 30 s without a key press and gave up after 10 minutes, while
  the guide was being browsed. It now waits for a 10 s pause, for as long
  as Kodi runs.
- Instances with no channel list (the "Migrated Add-on Config" Kodi makes
  when IPTV Simple is installed again) are removed once KodiMov+'s own
  instance exists.

 - **One IPTV Simple instance per channel list**: the TV guide setup rewrites the instance that already reads KodiMov+'s list (one set up with the original add-on, or by hand) instead of adding `instance-settings-91.xml` next to it, and the service deletes any extra one at Kodi start (keeping the one that isn't 91, which holds what was watched): two of them showed every channel twice.
 - Fixes the programme guide export of upstream 1.0.0 (the amazon.tv guide is a flat list).
 - Its own proxy port (57031), so it can run next to the original. After an update the new proxy waits for the old one to free the port instead of moving to a random one, so the channel being watched keeps playing (upstream sets `allow_reuse_address` and `SO_REUSEADDR` too late to take effect).
-- **Restarts IPTV Simple only while idle**: nothing playing and no key pressed for 30 seconds (a channel opened during a restart fails). After start or update a single guide reload also picks up changed instance files.
+- **Restarts IPTV Simple only while idle**: nothing playing and no key pressed for 10 seconds (a channel opened during a restart fails). It waits for that as long as Kodi runs: after the box was off, Kodi first loads the old guide file and keeps it (no current programmes) until the reload. After start or update a single guide reload also picks up changed instance files.
+- **Removes empty IPTV Simple instances** (no channel list, like the "Migrated Add-on Config" Kodi creates when IPTV Simple is installed again) once KodiMov+'s own instance is there.
