Auth stack certs tab, arrs db fallbacks, cert monitor cache, conf parser fix

- Auth stack: fold cert monitor into Auth Stack page as fourth tab (Certs);
  remove standalone cert page and top-level tab
- cert_monitor.sh: write JSON status cache to State_Files/cert_status.json
  after each run; expose per-domain days/expiry via _CERT_DAYS/_CERT_EXPIRY globals
- api/cert.php: new — serves cached cert status; falls back to configured
  domains as UNKN when no cache exists; POST action=run triggers live check
- arrs db fallbacks: vv_arr_cleanup_stats/discovery_stats/recovery_stats now
  read from data/*.db files when log JSON files don't yet exist
- config.php vv_conf_vars(): unescape bash \$ → $ so passwords with dollar
  signs read correctly from conf files
- host1.conf: fill in HOST1_NPM_USER/PASS and HOST1_LLDAP_USER/PASS
- Partnership adapter pattern: Unraid-specific container logic extracted to
  Plugin/unraid/Partnership/; platform-agnostic structure stays in Partnership/
- First-run wizard: uniform multi-step flow for all hosts; HOST2 pull moved
  to checklist; auto SSH keygen and API key creation on save
- api/checklist.php: live setup checklist with pull_master action
- Fullscreen toggle: hide Unraid header/menu; state persists via localStorage
