Closes #3600. Previously the From header on test emails and notifications showed only the raw email address. Adds an optional "Sender name" field so emails appear from a friendly name like "Checkmate notifications" <user@example.org>. ## Behaviour - Field is optional. When empty/null/whitespace, the From header falls back to the raw email address — identical to current behaviour, no regression for existing installs. - When set, the email service hands nodemailer { name, address } as the message from field. Nodemailer handles RFC-5322 encoding (quotes, commas, non-ASCII) so the display name is safe for any input. - Unsetting works: clearing the input transforms the value to null in the Zod parse step, and the settings repository already turns null values into a $unset operation. - Both client and server Zod schemas trim and empty-string-to-null, preventing whitespace-only display names from being stored. ## Surfaces - AppSettings schema, Settings type, EmailTransportConfig pick, server Zod validation, client Zod validation, client form defaults, and the Settings page form all carry the new systemEmailDisplayName field. - The transport preview pre-block on /settings now includes a `from` key showing exactly what the email service hands nodemailer — the string when no display name is set, or { name, address } when it is. - en.json carries the new label and placeholder. Other locales fall back until translated (16 locales pending — separate follow-up). ## Conventions conformance (per docs/frontend-conventions.md) - The pre-block I touched had three rule #1 violations (sx p, borderRadius, backgroundColor); hoisted those to native props using theme.shape.borderRadius. Other rule #1 violations elsewhere on this page are pre-existing and intentionally left alone. - No new sx-with-native-equivalents introduced. - No color="text.X" shorthand introduced. - No theme module import introduced.
Checkmate backend
The backend service for Checkmate, an open source uptime and infrastructure monitoring application
