AI category-aware evaluation: per-round config, file parsing, shortlist, advance flow

- Per-juror cap mode (HARD/SOFT/NONE) in add-member dialog and members table
- Jury invite flow: create user + add to group + send invitation from dialog
- Per-round config: notifyOnAdvance, aiParseFiles, startupAdvanceCount, conceptAdvanceCount
- Moved notify-on-advance from competition-level to per-round setting
- AI filtering: round-tagged files with newest-first sorting, optional file content extraction
- File content extractor service (pdf-parse for PDF, utf-8 for text files)
- AI shortlist runs independently per category (STARTUP / BUSINESS_CONCEPT)
- generateAIRecommendations tRPC endpoint with per-round config integration
- AI recommendations UI: trigger button, confirmation dialog, per-category results display
- Category-aware advance dialog: select/deselect projects by category with target caps
- STAGE_ACTIVE bug fix in assignment router
