Rewrite writeErr(w, err) to wrap *apierror.Error via apierror.From,
preserving the existing {"error": {"code", "message"}} wire envelope.
Add writeErrWithLog helper for 500-class errors that need an operator
log line. Migrate all 13 admin_*.go handler files (~76 call sites) to
the new signature; T3 will sweep the remaining api package.
The old 4-arg writeErr is removed, so non-admin call sites in
internal/api will not compile until T3 lands. This is by design — T2
and T3 are paired.

Three endpoints for the admin Settings UI:
- GET /api/admin/cover-sources — lists registered providers with
current settings + capability badges + sources_version
- PATCH /api/admin/cover-sources/{provider_id} — updates enabled
and/or api_key; returns version_bumped: true only when the
enabled set changed
- POST /api/admin/cover-sources/{provider_id}/test — invokes
TestableProvider.TestConnection; returns ok:bool + duration_ms +
error string. Returns 200 in both success and failure cases (the
operation completed; the test result is data, not an error).
api_key is never echoed in GET — replaced with api_key_set: bool
to follow the standard credential-display convention. PATCH
api_key: "" clears; omitting the field leaves it unchanged. PATCH
on an unknown provider_id returns 404.
All under existing RequireAdmin middleware. Routes registered
alongside the library/coverage endpoint in the /api/admin/ tree.
handlers struct gains a coverSettings *coverart.SettingsService
field; server.New + cmd/minstrel/main.go plumb the existing
coverSettings instance through.
coverart.ResetRegistryForTests() exported wrapper added so api
package tests can reset the registry without importing internals.
