fix: player connectivity and media download pipeline

- nginx: add /api/ shortcut block (no portal auth, X-Script-Name /digiserver,
  Host $http_host) so players can reach DigiServer API without /digiserver prefix
- nginx: use $http_host in /api/ block so Flask host_url includes port — fixes
  media download URLs missing :8080 (was http://ip/digiserver/... not http://ip:8080/...)
- player main.py: fix double-port bug when server_ip already contains a port
  (e.g. 192.168.0.230:8080 was producing http://192.168.0.230:8080:80)
- get_playlists_v2.py: force re-sync when server version differs OR local media
  files are missing on disk — fixes stale playlist after server reset
- digiserver api.py: playlist endpoint builds full media URLs using script_root
  from X-Script-Name header set by nginx
- weblink support, player build/deploy improvements, manage-playlist AJAX prefix fix
