fix(providers): respect user-configured baseUrl for kimi-coding (#36647)

* fix(providers): respect user-configured baseUrl for kimi-coding

The kimi-coding provider was built exclusively from
`buildKimiCodingProvider()` defaults, ignoring any user-specified
`baseUrl` or other overrides in `openclaw.json` providers config.
This caused 404 errors when users configured a custom endpoint.

Now merge `explicitProviders["kimi-coding"]` on top of defaults,
matching the pattern used by ollama/vllm. User's `baseUrl`, `api`,
and `models` take precedence; env/profile API key still wins.

Fixes #36353

 ### Fixes
 
 - Moonshot CN API: respect explicit `baseUrl` (api.moonshot.cn) in implicit provider resolution so platform.moonshot.cn API keys authenticate correctly instead of returning HTTP 401. (#33637) Thanks @chengzhichao-xydt.
+- Kimi Coding/provider config: respect explicit `models.providers["kimi-coding"].baseUrl` when resolving the implicit provider so custom Kimi Coding endpoints no longer get overwritten by the built-in default. (#36353) Thanks @2233admin.
 - Cron/proactive delivery: keep isolated direct cron sends out of the write-ahead resend queue so transient-send retries do not replay duplicate proactive messages after restart. (#40646) Thanks @openperf and @vincentkoc.
 - TUI/chat log: reuse the active assistant message component for the same streaming run so `openclaw tui` no longer renders duplicate assistant replies. (#35364) Thanks @lisitan.
 - macOS/Reminders: add the missing `NSRemindersUsageDescription` to the bundled app so `apple-reminders` can trigger the system permission prompt from OpenClaw.app. (#8559) Thanks @dinakars777.
