- Add NonEmploymentEntityPatterns dictionary with 10 categories of non-employer entities
(clubs, associations, trusts, charities, investment, property, religious, sports, educational, professional)
- Expand SkipWords from ~30 to 120+ words for better core identifier extraction
- Add GetSearchEntityTypes() and IsValidEmploymentEntity() helper methods
- Refactor FindBestMatch() to use pattern-based filtering instead of hardcoded checks
- Fix UI showing duplicate points for same company appearing multiple times
(now only shows points on first occurrence, subsequent rows show 0)
