feat: disable unused packages via ComfyUI Manager

Add per-package and per-section "Disable" buttons on the Safe to Remove
and Consider Removing tiers. Uses ComfyUI Manager's queue API
(/customnode/installed, /manager/queue/disable|start|status) to move
packages into custom_nodes/.disabled, reconciling against Manager's
actual state and surfacing a restart banner. Hidden when Manager is
absent.

Also:
- tracker: extract shared _classify_age() recency helper (DRY), add tests
- js: centralize STATUS_META, replace inline hover handlers with CSS,
  de-duplicate summary bar
- bump version to 1.2.0, update README
