play_state_sync: fix jq combine fallback + detect_hosts; load_config: fix word-split on paths with spaces

play_state_sync.sh:
- Add detect_hosts() call so TRANSCODE_SERVERS alias is populated
- Switch MEDIA_SERVERS → TRANSCODE_SERVERS (correct array name from host*.conf)
- Fix malformed jq fallback in combine step (was {"} now handled with if/else)
- Skip placeholder API keys in _add_server

load_config.sh:
- Replace 'for x in $(ls glob)' with 'while read < <(printf glob | sort)'
  so paths with spaces (e.g. dev workspace) don't get word-split
