fix(apollo): harden people_search pagination, correct bulk-update output docs

- people_search: read pagination from both the nested `pagination` object
  (legacy /mixed_people/search) and top-level fields, avoiding silent
  fallback to defaults
- account_bulk_update: correct output descriptions — accounts support up to
  1000 per request and async is opt-in (not auto-triggered at 100 like contacts)
