Introduce DNS monitoring: add DnsService (comprehensive DNS lookup, crt.sh discovery, Cloudflare detection, IP enrichment) and a new DnsRecord model to persist snapshots, manage diffs, and provide queries/stats. Update DomainController to support a dns_monitoring_enabled flag, refactor WHOIS/DNS refresh logic into performWhoisRefresh/performDnsRefresh, and add endpoints for refreshWhois, refreshDns and refreshAll; send notifications when DNS monitoring is toggled. Add UI templates/tabs for DNS, billing, notifications, overview, SSL and WHOIS and wire DNS data into the domain view; expose cached IP details. Add cron/check_dns.php and migration 027_add_dns_monitoring.sql (and include it in installer migration lists). Other tweaks: safer EmailHelper subject handling, TldRegistry search improvements, domain sorting using an effective status (expiring_soon), Discord channel null-safe fields, settings UI additions (domain_view_template and cron staleness warnings), and route/migration updates. This enables scheduled and manual DNS scans with persistent records and notifications.
Add CSV/JSON export and import endpoints and UI for the TLD registry, plus a manual Create TLD modal and drag-and-drop import UX. Standardize import/export logging by adding Logger('import'/'export') calls to Domains, Tags, Notification Groups and TLD flows. Add TldRegistry model helpers (findByTld, getAll) used for deduplication and exports. Update routes for /tld-registry export/import/create and add a migration to bump app_version to 1.1.4. Also update default app_version, enhance WhoisService parsing (registrar regex and ISO-8601 date handling), and adjust the TLD registry index view to include IANA and Export dropdowns, import modal, create modal, and related JS behavior.
