feat: overhaul OpenClaw config panels with JSON5 round-trip write engine

- Add json-five crate for JSON5 serialization preserving comments and formatting
- Rewrite openclaw_config.rs with comment-preserving JSON5 read/write engine
- Add Tauri commands: get_openclaw_live_provider, write_openclaw_config_section
- Redesign EnvPanel as full JSON editor with structured error handling
- Add tools.profile selection (minimal/coding/messaging/full) to ToolsPanel
- Add legacy timeout migration support to AgentsDefaultsPanel
- Add OpenClawHealthBanner component for config validation warnings
- Add supporting hooks, mutations, utility functions, and unit tests
