feat(mcp): app-aware MCP panel and Codex MCP sync to config.toml

- Make MCP panel app-aware; pass appType from App and call APIs with current app
- Show active app in title: “MCP Management · Claude Code/Codex”
- Add sync_enabled_to_codex: project enabled servers from SSOT to ~/.codex/config.toml as [mcp.servers.*]
- Sync on enable/disable, delete, and provider switch (post live write)
- Add Tauri command sync_enabled_mcp_to_codex and expose window.api.syncEnabledMcpToCodex()
- Fix Rust borrow scopes in switch_provider to avoid E0502
- Add TS declarations for new Codex sync API
