fix: deploy uses wrong env vars and kimi model sent to Z.ai API

Root cause of "kimi-k2.5 is not a valid model ID" error:

1. deploy-hostinger.yml set PICOCLAW_PROVIDERS_ZHIPU_API_KEY which
   was never read (broken {{.Name}} env tags). Changed to
   PICOCLAW_ZAI_API_KEY which loadProviderEnvVars() reads correctly.

2. deploy-hostinger.yml set provider to "zhipu" instead of "zai".

3. When kimi model names (kimi-k2.5) were routed to Z.ai due to
   missing Moonshot key, the incompatible model name was sent as-is.
   Now swaps to "glm-4.7" when kimi models fallback to Z.ai.

4. full-deploy.sh: added "zai" provider case with glm-4.7 default,
   updated zhipu ENV_KEY_NAME to ZAI_API_KEY.
