feat: add Token Plan quota query for Kimi, Zhipu GLM, and MiniMax

Add a new "Token Plan" template type in the usage query panel that
natively queries quota/usage from Chinese coding plan providers
(Kimi For Coding, Zhipu GLM, MiniMax) without requiring custom scripts.

- Rust backend: new coding_plan service with provider-specific API
  queries (Kimi /v1/usages, Zhipu /api/monitor/usage/quota/limit,
  MiniMax /coding_plan/remains) normalized into UsageResult
- Frontend: Token Plan template in UsageScriptModal with auto-detection
  of provider based on ANTHROPIC_BASE_URL pattern matching
- Follows the same pattern as GitHub Copilot template (dedicated API
  path in queryProviderUsage, no JS script needed)
