fix(admin-web): align provider surface with backend and ADR-0024

The org-admin provider page was a stale prototype wired to a removed
singular /provider-connection endpoint. It contradicted the pinned
invariants in several ways:

- It documented a process-env fallback for platform-managed credentials,
  but ADR-0024 / Spec.System.Organization pins the resolver fail-closed
  with no process-global key fallback.
- It exposed a BYOK<->PLATFORM_MANAGED mode toggle to org admins, but
  ADR-0021 makes platform-managed connections platform-admin owned; the
  org-side API (requireByokActor) rejects mutating them.
- It modeled one connection per org, while OrganizationProviderConnection
  is keyed by (org, providerId) and the backend exposes a list plus a
  per-providerId BYOK rotation.
- Its HTTP contract (/provider-connection, {baseUrl, hasAuthToken}) did
  not match the real backend (/provider-connections + /:providerId,
  {status, activeVersion, keyId}).
- It dangled a pointer to role/model pages that do not exist in the SPA;
  roles/skills are managed via the CLI.

Rewrite the page to list connections, show status/version/keyId, and
rotate BYOK credentials per providerId with baseUrl + authToken (+ optional
anthropicApiKey) as the backend requires. Platform-managed rows render
read-only. Drop the fallback copy and the dangling pointer. Replace the
singular ProviderConnection API client with providerConnections /
rotateProviderConnection and remove the now-unused PROVIDER_MODES constant.
