- Discord embeds don't support newlines in description field
- Use comma-separated list format for Discord grouped alerts
- Keep escaped newlines for other webhook providers (Telegram, Slack, Teams)
- Prevents JSON parsing errors with Discord webhook API
Discord now shows: "Alert | 🔔 5 alerts: • item1: 25.4%, • item2: 11.6%, ..."
Other providers show multi-line format with proper escaping.
- Show full list of grouped alerts for Discord, Slack, Teams, etc (not just Telegram)
- Properly escape newlines in grouped alert messages to prevent JSON parsing errors
- Ensure consistent formatting across all webhook providers
- Address issue where only custom templates showed complete alert lists
All webhook providers now display the same detailed grouped alert format with bullet points showing each alert's resource and value.
Webhooks weren't being sent because the grouped alert message contained actual
newlines which broke JSON parsing in custom templates. Changed to use escaped
newlines (\n) which work properly in JSON strings.

- Addresses user reports of webhook delivery issues
- Use realistic test values (85.5% CPU, 80% threshold) instead of zeros
- Set alert level to 'warning' instead of 'info' for better visibility

Addresses #305
- Fix Discord webhook templates to use logo.svg instead of non-existent favicon.svg
- Add comprehensive release notes for v4.3.0 about embedded frontend breaking change
- Document migration path and benefits of embedded frontend
The embedded frontend is a significant architectural improvement that eliminates
path-related issues but requires clear communication to users about the change.
Fixed two critical issues with email notifications:
1. Test email API now returns errors properly instead of always showing success
2. Added timeouts to SMTP connections to prevent hanging (10s dial, 30s overall)
The root cause of users not receiving emails was that errors were being
silently logged instead of returned to the API, making it appear successful
when it wasn't. SMTP connections could also hang indefinitely on unreachable
servers.
Note: API uses "server" and "port" JSON fields, not "smtpHost"/"smtpPort"
Frontend fixes:
- Fixed VM thresholds incorrectly showing as 'CT' in alerts UI (issue #295)
- Fixed threshold slider not reaching 0% and 100% edges (issue #295)
- Fixed PBS form auto-filling with PVE settings (issue #296)
- Fixed email config property mapping (server/port instead of smtpHost/smtpPort)
Backend fixes:
- Updated EmailConfig struct to use 'server' and 'port' JSON tags for consistency
- Added 'provider' and 'startTLS' fields to EmailConfig
- Fixed PORT env var to correctly set FrontendPort instead of BackendPort
- Changed default log level from Debug to Info
All changes tested and verified working correctly.
