AI tag/category assignment + phone extraction from web ads

AI (when enabled, now that the server proxy is up):
- AiStructured gains phone, personName, yearsExperience, isLicensed.
- The auditor appends an authoritative output-schema to the admin prompt
  so classification stays correct even with an older stored prompt — it
  now classifies kind as shift|job|talent and extracts the contact phone
  and talent details.
- Ingestion publish prefers the AI's tags (kind/role/city/facility/phone +
  talent fields) over the heuristic parser when present.
- Default prompt updated to describe the three kinds + new fields.

Phone extraction from websites (Medjobs / generic sites), where the
number sits behind a "تماس با این آگهی" reveal:
- HtmlUtil.HarvestPhones scans the full markup for tel: links, JSON-LD
  "telephone", data-*phone* attributes, and inline Iranian mobile/landline
  numbers (Persian digits folded), normalized (mobiles 09…, landlines 0…).
- Medjobs + Website sources append harvested numbers to the ad text so the
  parser/AI capture them; manual review then prefills the phone too.
- Parser phone extraction now also captures a landline as a fallback.

Note: if a site loads the number purely via XHR (not in HTML), a
per-source reveal endpoint would be a follow-up.
