Update project documentation and improve frontend functionality

- Updated the backend documentation in CONTRIBUTING.md and README.md to reflect changes in application structure and API endpoints.
- Enhanced the frontend components in MapView.vue for better handling of context menu actions.
- Added new types and interfaces in TypeScript for improved type safety in the frontend.
- Introduced new utility classes for managing characters and markers in the map.
- Updated .gitignore to include .vscode directory for better development environment management.

Пути к `frontend/` и `public/` задаются из рабочей директории при старте; шаблоны встроены в бинарник (webapp, `//go:embed`).
