Two cleanups in one pass for the v1.14.0 'works on any platform' theme:
1. Response helpers — merged src/utils/responses.js and the root-level
response-helpers.js into a single module at src/utils/responses.js.
The old module had a richer set (created, noContent, validationError,
unauthorized, forbidden, notFound, conflict) and is now re-exported
from the new location. Updated 15 routes to import from
src/utils/responses and deleted the root response-helpers.js.
2. Error logger — error-handler.js now uses the unified
src/utils/logging.js#logError (same one src/app.js uses), so all errors
go to one log file with one rotation policy. Removed the dead
asyncHandler export (the real one is in src/utils/async-handler.js
and is used everywhere). Deleted the legacy error-logger.js.
Both are invisible to users — same HTTP response shapes, same log file
path, same error format. Internal-only refactor.
- dns-providers/: adapter base class + registry with auto-discovery
- technitium.js: wraps existing Technitium API calls into adapter interface
- cloudflare.js: Cloudflare API v4 adapter (zones, records, credentials)
- rfc2136.js: RFC 2136 dynamic DNS via nsupdate (BIND, PowerDNS, etc.)
- manual.js: no-op adapter for external DNS management with instructions
- provider-dns.js: provider-aware DNS context, resolves active adapter from config
- Universal helper methods: universalCreateRecord/Delete/ResolveRecord
- All 7 route files updated to use universal methods instead of raw dns.call()
- Setup wizard: provider dropdown (Technitium, Cloudflare, RFC 2136, Manual)
- DNS template selector: added Cloudflare and External/Manual options
- Config schema: validates dns.provider field
- Capability gating on Technitium-specific endpoints (logs, restart, update)
- Backward compatible: no provider set = auto-detect (technitium if dns.ip exists)
