Fix: site-wide phone on every Medjobs ad + phone mistaken for price

- HarvestPhones was run over the whole page, so Medjobs' own header/footer
  number (09101016110) was appended to every ad. Now harvest only the ad's
  description region in Medjobs + Website sources; the protected number
  still comes from the reveal call. No more duplicate number across ads.
- The amount extractor read phone digits as a Toman price
  (۹,۱۰۱,۰۱۶,۱۱۰ تومان). The parser now strips «شماره تماس…» lines and
  mobile/landline numbers before extracting money, and only accepts 6–10
  digit numbers with no leading zero (phones/ids start with 0 or are 11+).
