Platform-wide visual overhaul, team invites, analytics improvements, and deployment hardening

UI overhaul applying jury dashboard design patterns across all pages:
- Stat cards with border-l-4 accent + icon pills on admin, observer, mentor, applicant dashboards and reports
- Card section headers with color-coded icon pills throughout
- Hover lift effects (translate-y + shadow) on cards and list items
- Gradient progress bars (brand-teal to brand-blue) platform-wide
- AnimatedCard stagger animations on all dashboard sections
- Auth pages with gradient accent strip and polished icon containers
- EmptyState component upgraded with rounded icon pill containers
- Replaced AI-looking icons (Brain/Sparkles/Bot/Wand2/Cpu) with descriptive alternatives across 12 files
- Removed gradient overlay from jury dashboard header
- Quick actions restyled as card links with group hover effects

Backend improvements:
- Team member invite emails with account setup flow and notification logging
- Analytics routers accept edition-wide queries (programId) in addition to roundId
- Round detail endpoint returns inline progress data (eliminates extra getProgress call)
- Award voting endpoints parallelized with Promise.all
- Bulk invite supports optional sendInvitation flag
- AwardVote composite index migration for query performance

Infrastructure:
- Docker entrypoint with migration retry loop (configurable retries/delay)
- docker-compose pull_policy: always for automatic image refresh
- Simplified deploy/update scripts using docker compose up -d --pull always
- Updated deployment documentation
