feat: v2.0 — maintenance module, AI analysis, station power fix
- Add full 检修维护中心 (6.4): 3-type work orders (消缺/巡检/抄表), asset management, warehouse, work plans, billing settlement - Add AI智能分析 tab with LLM-powered diagnostics (StepFun + ZhipuAI) - Add AI模型配置 settings page (provider, temperature, prompts) - Fix station power accuracy: use API station total (station_power) instead of inverter-level computation — eliminates timing gaps - Add 7 new DB models, 4 new API routers, 5 new frontend pages - Migrations: 009 (maintenance expansion) + 010 (AI analysis) - Version bump: 1.6.1 → 2.0.0 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
