feat(core): 新增讯飞 Astron CodingPlan + 修正 spark / volcengineCodingPlan

讯飞（iFLYTEK）补完：
- 新增 astronCodingPlan endpoint（讯飞星辰 MaaS 针对编程场景的订阅服务）
  baseUrl: https://maas-coding-api.cn-huabei-1.xf-yun.com/anthropic
  走 Anthropic 兼容协议，统一 model id 是 astron-code-latest
- spark.ts 按官方 HTTP API 文档重写模型清单：
  · 删除 bank 私造的 spark-x / x1（官方文档无此 id）
  · 修正各模型的 context/output 边界（4.0Ultra 32K/32K，pro-128k 128K/32K 等）

火山 Coding Plan：
- baseUrl 修正为 /api/coding（旧的 /api/v3/anthropic 是通用 Anthropic 接入，
  和 CodingPlan 订阅计量不通，会导致 401 / 配额扣错）
- 补齐 Doubao-Seed-2.0 (code/pro/lite) 全家桶
- 规范化第三方模型 id 大小写（MiniMax-M2.5 → minimax-m2.5，和火山实际接受值一致）
- 删除无效的 deploymentName（火山 CodingPlan 的 id 即请求体 model 字段，
  无需 alias 映射）

providers-schema.test 随总 endpoint 数 42 → 43 更新
