feat(dns): add custom DNS provider plugin system

- Add plugin interface with lifecycle hooks (Init/Cleanup) - Implement thread-safe provider registry - Add plugin loader with SHA-256 signature verification - Migrate 10 built-in providers to registry pattern - Add multi-credential support to plugin interface - Create plugin management UI with enable/disable controls - Add dynamic credential fields based on provider metadata - Include PowerDNS example plugin - Add comprehensive user & developer documentation - Fix frontend test hang (33min → 1.5min, 22x faster) Platform: Linux/macOS only (Go plugin limitation) Security: Signature verification, directory permission checks Backend coverage: 85.1% Frontend coverage: 85.31% Closes: DNS Challenge Future Features - Phase 5
