4833ee1ff9 fix: Complete ProtonBridge email integration with missing templates 
- Fix HTML rendering in emails (triple braces for raw HTML in base template)
- Add missing email content templates (project-updates, implementation-notes, governance-discussions)
- Simplify SMTP port detection to respect .env configuration
- Exclude email-templates from CSP validation (inline styles required for email clients)
- Restore EMAIL_FROM to newsletter@agenticgovernance.digital

All templates now exist, emails render correctly, and ProtonBridge integration is complete.

8b9f946a4a feat: Migrate from SendGrid to ProtonBridge for email sending 
Complete migration to ProtonBridge following proven family-history architecture:

Backend Changes:
- Replace @sendgrid/mail with nodemailer
- Refactor EmailService for ProtonBridge/SMTP
- Add smart port detection (1026 prod, 1025 dev)
- Implement connection pooling and rate limiting
- Add EMAIL_ENABLED flag for dev/prod separation
- Add checkConnection() method for health checks

Email Service Features:
- Localhost-only SMTP (127.0.0.1)
- Automatic production/development port detection
- Connection verification on initialization
- Connection pooling (max 5 connections)
- Rate limiting (10 messages/second)
- Graceful fallback when email disabled

Documentation:
- Complete ProtonBridge setup guide (VPS installation)
- Quick start guide (30-minute setup)
- Systemd service file template
- Environment variable configuration
- Troubleshooting guide
- Migration notes from SendGrid

Architecture Benefits:
- Privacy-focused (end-to-end encrypted via Proton)
- Self-hosted bridge on VPS (no third-party API)
- Validated in production (family-history: 3+ months, 315+ restarts)
- Cost-effective (Proton paid account ~$4/month)
- No external dependencies (localhost SMTP)

Next Steps:
1. Install ProtonBridge on production VPS
2. Update production .env with Bridge credentials
3. Deploy email service changes
4. Test newsletter sending

See docs/PROTONBRIDGE_QUICKSTART.md for deployment guide
