feat(competitor-analysis): Fix 404, SDK compatibility, and update docs

Resolved multiple issues preventing the 'competitor-analysis' app from running and serving its frontend:

1.  **Fixed Python SyntaxError in Prompts:** Corrected unterminated string literals and ensure proper multi-line string formatting (using .format() instead of f-strings for complex prompts) in .
2.  **Addressed Python SDK Compatibility (google-generativeai==0.3.0):**
    *   Removed  for  and  by adapting the orchestrator to pass JSON schemas as direct Python dictionaries, as required by the older SDK version.
    *   Updated  with detailed guidance on handling / imports and dictionary-based schema definitions for older SDKs.
3.  **Corrected Frontend Build Dependencies:** Moved critical build dependencies (like , , ) from  to  in .
    *   Updated  to include this  pitfall, ensuring frontend build tools are installed in Docker.
4.  **Updated Documentation:**
    *   : Added comprehensive lessons learned regarding  dependencies, Python SDK versioning (specifically  and  imports for ), and robust multi-line prompt handling.
    *   : Integrated specific details of the encountered errors and their solutions, making the migration report a more complete historical record and guide.

These changes collectively fix the 404 error by ensuring the Python backend starts correctly and serves the frontend assets after a successful build.
