Wire DefaultDevResolver into all three components when running in dev mode. This enables .test TLD handle resolution via the local PDS's XRPC endpoint.
- appview: uses existing config.Pds.Host for the PDS URL
- knotserver: uses hardcoded localhost:2583 (PDS runs inside the VM)
- spindle: same as knotserver
No new config fields are added to knot or spindle.
