Applicants: auto-tags + deep search w/ highlight; never delete (archive instead)

- Tags: parser extracts cert/skill keywords (mmt, ICU/CCU, دیالیز, اتاق عمل,
  اورژانس, مسئول فنی, پروانه‌دار…) + role + city into TalentListing.Tags
  (+ migration); shown as chips on cards.
- Deep search on /Talent: «جستجوی عمیق» box does Postgres ILIKE across
  tags, description, person, area, role, city (every term must match);
  matches are highlighted with <mark> via SearchHighlight.
- Never delete: ShiftStatus.Archived + the admin «بایگانی گروهی» action now
  ARCHIVES aggregated posts (hidden from site, kept in DB) and leaves the
  raw crawl rows intact — a permanent archive for future analytics.
