refactor: extract shared validation and reduce duplication

- Extract tool_types validation to shared module (validate_compose_yaml, check_port_exposed, validate_required_variables)
- Extract _get_user and _get_owned_project to auth/dependencies.py
- Create useAsyncData hook and apply to 6 pages
- Create extractErrorMessage utility
- TypeScript and build pass
