Environment configuration

SMTP_PASSWORD=
SMTP_FROM=Slack and Telegram credentials are stored per channel in the database.
Testing
Create a test rule with a short duration threshold on a demo tag, attach your channel, and verify delivery. For HTTP, inspect the webhook test log at GET /api/webhooks/test/log.
Permissions
