feat(proxy): add OpenCode IDE config and fix service availability

- Add opencode to SupportedIde with JSON providers.json output
- Add defaultModel parameter for IDE config generation
- Add model selector dropdown in ToolsTab for IDE configurations
- Use getServiceOptional for graceful degradation when proxy is stopped
- Add fallback IDE config generation using ConfigManager when NestJS is offline
- Update IPC router schema to accept defaultModel parameter
