Implemented all 5 critical efficiency improvements to optimize
performance, reduce resource usage, and improve scalability.
## 1. Database Indexes
- Added indexes on sermon_notes foreign keys (user_id, sermon_id)
- Added composite index on sermons (archived, date DESC)
- Added indexes on frequently queried columns across all tables
- Impact: Faster queries as data grows, better JOIN performance
## 2. Eliminated N+1 Query Pattern
- Reduced 2 API calls to 1 on home page load
- Changed from separate active/archived fetches to single call
- Filter archived sermons client-side using computed properties
- Impact: 50% reduction in HTTP requests per page load
## 3. Scheduled Database Cleanup
- Extended existing plugin to clean expired sessions hourly
- Added cleanup for expired rate limits every hour
- Added cleanup for expired password reset codes every hour
- Sermon cleanup continues to run daily based on retention policy
- Impact: Prevents database table growth, better performance
## 4. Multi-stage Docker Build
- Implemented 3-stage build: deps -> builder -> runtime
- Separated build-time and runtime dependencies
- Added non-root user (nuxt:nodejs) for security
- Integrated dumb-init for proper signal handling
- Added health check endpoint at /api/health
- Impact: Smaller image size, faster deployments, better security
## 5. HTTP Caching
- Static assets: 1 year cache (immutable)
- Logos/images: 1 year cache (immutable)
- API routes: No cache (always fresh)
- HTML pages: 10 minute cache with revalidation
- Impact: Reduced bandwidth, faster page loads, less server load
All optimizations follow best practices and maintain backward
compatibility with existing functionality.

Simplified email configuration to always use process.env directly instead of
Nuxt runtime config. This ensures Docker environment variables are properly
read at runtime rather than being baked in at build time.
Changes:
- Removed Nuxt runtime config dependency from getEmailConfig()
- Always read EMAIL_* environment variables directly from process.env
- Added comprehensive debug logging to diagnose configuration issues
- Updated nuxt.config.ts with better documentation of runtime config behavior
This ensures environment variables set in docker-compose.yml are properly
used by the application at runtime.
