AI网关新增xAI格式TTS端点与过滤弃用模型开关

- POST /ai/v1/tts:xAI 官方 TTS 格式转换层(text/voice_id→input/voice),复用 Speech 编排,model 缺省 xai.grok-tts;实测 output_format/speed 透传生效 - 「过滤弃用模型」开关(GET/PUT /api/v1/ai-settings,settings 表持久化):开启后已宣布弃用(未退役)模型从列表与路由排除;同步入库与退役提醒不受影响 - AI 网关文档更名 docs/AI网关.md,补 tts 矩阵段与开关说明;README 引用同步 - CHANGELOG 0.5.0(0.4.0 已发版冻结);DASH_VERSION v0.5.0
