fix: Use direct process.env access for email configuration

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.
