Implement 10 platform features: evaluation UX, admin tools, AI summaries, applicant portal

Batch 1 - Quick Wins:
- F1: Evaluation progress indicator with touch tracking in sticky status bar
- F2: Export filtering results as CSV with dynamic AI column flattening
- F3: Observer access to analytics dashboards (8 procedures changed to observerProcedure)

Batch 2 - Jury Experience:
- F4: Countdown timer component with urgency colors + email reminder service with cron endpoint
- F5: Conflict of interest declaration system (dialog, admin management, review workflow)

Batch 3 - Admin & AI Enhancements:
- F6: Bulk status update UI with selection checkboxes, floating toolbar, status history recording
- F7: AI-powered evaluation summary with anonymized data, OpenAI integration, scoring patterns
- F8: Smart assignment improvements (geo diversity penalty, round familiarity bonus, COI blocking)

Batch 4 - Form Flexibility & Applicant Portal:
- F9: Evaluation form flexibility (text, boolean, section_header types, conditional visibility)
- F10: Applicant portal (status timeline, per-round documents, mentor messaging)

Schema: 5 new models (ReminderLog, ConflictOfInterest, EvaluationSummary, ProjectStatusHistory, MentorMessage), ProjectFile extended with roundId + isLate.
