feat(gtm-architect): Finalize migration and implement web scraping

- Refactors the gtm-architect Dockerfile for a flat, more efficient build process.
- Implements robust web scraping via BeautifulSoup in helpers.py for URL analysis in phase1.
- Makes shared library imports (gspread, pandas, etc.) in helpers.py optional to prevent ModuleNotFoundErrors in microservices.
- Implements the main execution logic in the orchestrator to handle command-line arguments.
- Updates documentation to reflect the new architecture, scraping feature, and dependency handling.
