Replace hardcoded Cloudflare DNS-01 with a data-driven provider registry supporting 11 providers (Cloudflare, Route 53, DigitalOcean, Duck DNS, Hetzner, Vultr, Porkbun, GoDaddy, Namecheap, OVH, Linode). Users can configure multiple providers with encrypted credentials and select a default. Per-certificate provider override is supported via providerOptions. - Add src/lib/dns-providers.ts with provider definitions, credential encrypt/decrypt, and Caddy config builder - Change DnsProviderSettings to multi-provider format with default selection - Auto-migrate legacy Cloudflare settings on startup (db.ts) - Normalize old single-provider format on read (getDnsProviderSettings) - Refactor buildTlsAutomation() to use provider registry - Add GET /api/v1/dns-providers endpoint for provider discovery - Add dns-provider settings group to REST API and instance sync - Replace Cloudflare settings card with multi-provider UI (add/remove providers, set default, dynamic credential forms) - Add 10 DNS provider modules to Caddy Dockerfile - Update OpenAPI spec, E2E tests, and unit test mocks Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
