fix(settings/agents): exclude noise from drift detection

Two false positives surfaced after the Agents tab went live:

1. status (running/idle/paused) is runtime state, not config — drops in
   and out as agents pick up issues. Removed from _DRIFT_FIELDS.

2. desiredSkills compared raw, but local/* and company/* skills carry
   per-company hashes/scopes by design (sync_agents_across_companies.py
   filters local skills with a warning). Comparing them flags every
   master+mirror pair that has any local skill on master.

Now compares only paperclipai/* skills (vendor-shipped, must match).
UI shows an inline note explaining the filter.
