Admin log routes moved under /v1/admin/logs/*

Patch Changes

• 31c2a64: Admin log routes moved under /v1/admin/logs/* on the API per issue #504 tier 3. The releases admin source fetch-log command and getUsageStats / postUsageLog / postFetchLog helpers are unchanged from the user's perspective, only the underlying URLs shift:
  • GET /v1/fetch-log → GET /v1/admin/logs/fetch
  • POST /v1/fetch-log → POST /v1/admin/logs/fetch
  • GET /v1/usage-log/stats → GET /v1/admin/logs/usage/stats
  • POST /v1/usage-log → POST /v1/admin/logs/usage
