feat: native disable/enable fallback and package whitelist; bump to 1.8.0

Disable/enable no longer require ComfyUI Manager:
- New pack_fs.py moves packs in/out of custom_nodes/.disabled/ (no import,
  delete, or re-clone). Fallback for hand-cloned packs, loose single-file
  nodes, or when Manager is absent. enable strips the @version suffix so
  packs restore as clean, importable dir names.
- Routes: native-disable, native-enable, disabled-packs.
- Frontend routes each disable per-pack (Manager queue vs native move), and
  shows an Enable button on recoverable packs in the Uninstalled tier. The
  restart banner degrades to a manual-restart notice when no Manager exists.

Whitelist (packages-only): a star toggle protects a pack — pulled into its
own pinned group, no Disable button, skipped by the 7-day trial auto-disable.
- New whitelist_packages table; whitelisted flag on package stats.
- Routes: whitelist, whitelist/add, whitelist/remove.

Tests: test_pack_fs.py, test_whitelist.py (60 passing).
