Add a guard ($isRichAlert) so rich (green-bar) Mattermost attachments are only created for domain expiration/SSL/status alerts (days_left, expiration_date, new_status, or hostname != domain). DNS-change alerts remain plain text. Remove the attachment text property and adjust field handling accordingly to keep formatting consistent and avoid creating attachments for irrelevant events.
Add comprehensive DNS management and input validation, plus safer transfer and logging behavior.
- Add CronHelper utilities for cron scripts and unify logging/formatting.
- Improve InputValidator: sanitizeDomainInput and validateRootDomain (handles multi-level TLDs) and use throughout domain import/create flows to reject subdomains.
- DomainController: refactor DNS refresh to support quick/deep discovery (background deep scans), add endpoints to discover, add/delete/bulk-delete DNS records, import BIND zone files, enrich IP metadata via enrichIpDetails, and strengthen bulk import/reporting messages.
- DnsRecord model: add source column handling (discovered/manual/imported), avoid auto-deleting manual/imported records, and add helpers for deleting, bulk deleting, manual adding and importing zone records.
- Tag, NotificationGroup and Domain transfer logic: unlink groups when ownership changes, remove tags that belong to other users, add audit logging via Logger and improved bulk transfer reporting. TagController/View: show transferable users for admins and skip global tags on transfer.
- Notification channels (Discord, Mattermost, etc.) and EmailHelper: allow explicit subjects and improve payload fields based on notification type.
- Add new migration 029_add_dns_record_source.sql and wire it into the installer; update migrations detection.
- Add new views/partials for confirm/import/transfer modals, update various domain/group/tag templates, and update cron scripts and routes for discovery.
These changes preserve manual/imported DNS records, improve root-domain validation, enable background deep discovery, and add better logging/audit trails for transfers and imports.
Introduces Mattermost as a new notification channel, including backend service integration, controller validation, UI form fields, and updates to channel type enums in the database schema and migrations. This enables users to configure and send notifications via Mattermost webhooks.
