feat: Initialize monorepo structure and comprehensive documentation

This commit establishes the new monorepo architecture for the KROW Workforce platform.

Key changes include:
- Reorganized project into `frontend-web`, `mobile-apps`, `firebase`, `scripts`, and `secrets` directories.
- Updated `Makefile` to support the new monorepo layout and automate Base44 export integration.
- Fixed `scripts/prepare-export.js` for ES module compatibility and global component import resolution.
- Created and updated `CONTRIBUTING.md` for developer onboarding.
- Restructured, renamed, and translated all `docs/` files for clarity and consistency.
- Implemented an interactive internal launchpad with diagram viewing capabilities.
- Configured base Firebase project files (`firebase.json`, security rules).
- Updated `README.md` to reflect the new project structure and documentation overview.
