Merge remote-tracking branch 'origin/master' into gitea/feature/end

Resolved conflicts taking origin/master (v0.5.55) as canonical, with local
features re-applied:
- runtime log level (LOG_LEVEL env + dashboard Settings → Logging, applied
  immediately and persisted across restarts)
- free/noAuth provider enable/disable toggle via providerStrategies.enabled
- parallel model testing (Test All Models / Test Selected Keys)

+// #2591 — Alibaba Intl key types split across two hosts:
+//   - alicode-intl: Coding Plan keys (sk-sp-...) → coding-intl.dashscope.aliyuncs.com
+//   - alims-intl:   standard DashScope API keys (sk-...) → dashscope-intl.aliyuncs.com/compatible-mode
+// The two key types are NOT interchangeable across hosts. Split into two providers
+// so each key type reaches its own host.
