feat: Implement unified Vue SPA with granular service control

Consolidate Reports and Data Entry apps into a single Vue.js SPA with:

Architecture:
- Module-based structure with lazy-loaded routes (@reports, @data-entry)
- Error boundaries per module to prevent cascade failures
- Dual API proxy in Vite for microservices (reports:8001, data-entry:8003)
- Pinia store factories for shared auth, company, and period stores
- Vite path aliases for clear module boundaries (@shared, @reports, @data-entry)

Service Management:
- Granular service control scripts (backend-reports.sh, backend-data-entry.sh, bot.sh, frontend.sh)
- 87% faster frontend restart: 7s vs 53s full restart
- 38% faster full startup: 33s vs 53s via parallel backend initialization
- Enhanced start-dev.sh with proper service timeouts (OCR: 30s, Vite: 15s, Bot: 10s)
- status.sh for comprehensive health checks

Features:
- Auto-select first company on login with period auto-load
- Hamburger menu with feature toggle support
- JWT token auto-injection via axios interceptors
- Unified header with company/period selectors
- IIS web.config for production deployment with multi-API routing

UX Improvements:
- Vue watchers for reactive company/period loading
- Lazy store initialization with graceful error handling
- Period persistence per user+company in localStorage
- Feature flags for optional modules

Deployment:
- Single IIS site serves unified frontend with API proxy rules
- Maintains separate backend processes for microservices
- Windows line ending fixes (.env CRLF → LF conversion)
