Multi-role ads: parse all roles + fan-out publish one listing per role

An ad like «استخدام پرستار سالمند و کودک و همراه بیمار» names several roles;
we kept only the first. Now:
- Parser collects ALL roles (ParsedListing.RoleNames): exact taxonomy
  matches (substring-deduped so پرستار⊂پرستار سالمندان) plus synonyms
  (سالمند→پرستار سالمندان, کودک/همراه بیمار→پرستار, اتاق عمل→تکنسین اتاق عمل…),
  capped at 4.
- Ingestion publishes one Shift/Job/Talent per resolved role (AI role +
  parser roles, distinct, capped), so each role is independently
  browsable and filterable. RawListing dedupe is unchanged (one raw → N posts).
