fix: systematic sweep of NON_ENGLISH_RE gaps in gender/compound notation

Audited all 2949 titles in jobs.csv against broader German-signal
heuristics than the regex itself uses, to find what it still misses:

- gender suffix generalized beyond slash/colon to also catch */_ and
  the adjectival -r form (Engineer*in, Mitarbeiter_in, Verantwortliche:r)
- 'und'/'oder' were missing entirely — basic conjunctions, zero
  English overlap
- occupational nouns (Mitarbeiter, Ingenieur, Berater, Leiter,
  Informatiker, Verantwortliche) now also match as compound suffixes
  (Aussendienstmitarbeiter, Vertriebsingenieur) instead of only
  standalone, since German compounds have no separator
- Berater, Leiter(in), Informatiker, Verantwortliche, unbefristet/
  befristet added — words that weren't on the list at all

Verified: 72 titles in jobs.csv history now correctly flag as
non-English that didn't before, all genuinely German on inspection;
re-ran the broad-heuristic audit after the fix and every remaining
candidate was a false positive from the heuristic itself (ambiguous
'Team', an English/German loanword).
