Bug fixes, arr cleanup API-driven scan, shared JS formatters

Bug fixes:
- fallback.sh: escape sed metacharacters (\ & |) in state_set values
- common.sh: parse PID from lock file content correctly (handles pid:metadata format)
- unraid_api_key_renew.sh: fix path depth (../../../) and sync registry key to conf when stale
- stop.php: only clear pid/status if process is actually dead — D-state survives SIGKILL
- array_started.sh: check ARRAY_START_SCRIPTS empty before printing launch header

Arr cleanup:
- radarr_cleanup.sh / sonarr_cleanup.sh: fetch root folders from arr API instead of
  reverse-looking up the path map — handles multi-root-folder setups correctly

UI:
- varaverk.js: extract shared formatters (_relTime, _fmtBytes, _sz, _uptime, _gb, _tb, _n)
- arrs.php / partnership.php: use shared formatters, remove duplicates
- arrs.php / fallback.php: show error message on fetch failure instead of silent empty
- docker.php: disable rename input during request, restore original value on failure
- setup.php: abort controller timeout on detect fetch
- partnership.php: remove Re-run Phase 2 button opacity dimming
