feat(kimi-coding): add Kimi Coding plan quota display (#279)

- Add getKimiUsage() with X-Msh-* device headers for Kimi API
- Parse weekly quota + rate-limit breakdown from /v1/usages endpoint
- Fix X-Msh-* headers in refreshKimiCodingToken (was missing)
- Wire kimi-coding into getUsageForProvider switch
- Add quota capability flag to providers.ts
- Remove console.warn/error (production-safe silent returns)
