POST /accounts now accepts secret as a provider-specific JSON object
instead of an opaque string, and validates credentials via
provider.Provider.Validate before persisting — invalid credentials get
a generic 400 without ever reaching Store.CreateAccount or echoing the
secret back.

Selectel Cloud DNS v2 requires a project IAM token in X-Auth-Token, not the
raw service-user secret; the previous client sent the static secret directly
and got 401. The client now parses Credentials.Secret as a Creds JSON blob
(username/password/account_id/project_name), exchanges it for a token via
the Identity API (POST /identity/v3/auth/tokens), and caches the token in
memory per-account until 5 minutes before expiry. ListZones/GetRecords/
ApplyChanges send the cached IAM token instead of the raw secret.
provider.Provider gains a Validate(ctx, Credentials) method so a bad account
can be rejected via trial login at creation time; all Provider fakes across
provider/registry/api/service test packages implement it as a no-op stub for
now (Task 2 will make api's mock configurable).
Security: the service-user password is folded into the token cache key via
SHA-256 (never stored in the clear) so a password change invalidates the
cached token; identity errors are generic and never echo the request body.

Task 5 Фазы 3: GET/PUT /schedule (дефолт при отсутствии строки, валидация
interval>=60), POST/GET/DELETE /channels (секрет шифруется Cipher, никогда
не возвращается в ответах), POST /channels/{cid}/test через узкий
TestSender-интерфейс (200/502 без утечки секрета), GET /domains/{did}/history
(сначала GetDomain для project-scoping, затем ListCheckRuns — иначе IDOR
через check_runs, который сам по себе не scoped по project).
Добавлены store.GetDomain (обёртка над существующим sqlc-запросом) и
store.ListCheckRuns (новый запрос + sqlc regen) для поддержки истории.
Task 9 Фазы 1B: узкий интерфейс TenantStore (внутри store.Account/Template/Domain,
без db.* в api) реализован тонкими обёртками в internal/store/tenant.go; API.Store/
Cipher/Reg добавлены к существующему Svc. Роуты POST/GET/DELETE для accounts/
templates/domains + POST /accounts/{aid}/import (ListZones -> CreateDomain на зону).
accountResponse не содержит секрет ни в каком виде.
