Switch CMOs and QAs to minimax/MiniMax-M2.7 direct (no OpenRouter)

CMOs (Savannah, Addison, Clipper):
- Switched from claude_local/sonnet to opencode_local/minimax
- Uses MINIMAX_API_KEY secret_ref (direct MiniMax API, not OpenRouter)
- opencode.json with web search MCP
- Removed .mcp.json (claude_local only)
- promptTemplate required in DB (no instructionsFilePath)

QAs (Betty, Regina, Lint Roller):
- Switched from openrouter/minimax to minimax direct
- Model: minimax/MiniMax-M2.7 (was openrouter/minimax/minimax-m2.7)
- Uses MINIMAX_API_KEY instead of OPENROUTER_API_KEY

VP Products: unchanged (stay on opus, .mcp.json for web search MCP only)
