Enhance DNS discovery, validation & transfers

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.
