feat(tts): 简化语言集到 6 个通用语种 + 大模型生成接 targetLanguage

v1: 只暴露 6 个常用通用语种(粤语属于方言,放 v2)。
- zh-CMN 普通话
- en-US  / en-GB 美式/英式英语
- ja-JP  日语
- ko-KR  韩语
- id-ID  印尼语

完整矩阵数据(15 lang_key)保留在 server 端,后续可加"高级选项"暴露。

大模型 prompt 改造:
- deep-plan.node.ts + plan.node.ts: 接收 targetLanguage,在 prompt 里写
  '全篇内容必须用{lang}撰写'。这样大模型按用户选的语言生成内容。
- 之前是默认中文(无论用户选什么),现在会按 lang 走。

文件:
- deploy-package/scripts/build-lang-matrix-json.js: RECOMMENDED 改为 6 个
- my-uniapp-vue3/src/utils/languages.ts: LANGUAGES_FALLBACK 改为 6 个
- server/src/config/alicloud-tts-lang-voice-matrix.json: 重新生成

完整链路:
用户选 ja-JP → pickTtsVendor(ja-JP) → loongtomoka 日语音色
             + plan/deep-plan prompt '全篇内容必须用日语撰写'
             → 大模型生成日语内容 → TTS 用日语音色朗读
             → 文本+音频一致
