API crashes on import when commonforms dependencies are missing

[SahilRakhaiya05]

While setting up the project in a clean environment, I noticed that just importing api.main crashes if dependencies like cv2, numpy, or ultralytics are not installed.

After debugging, this seems to come from a top-level import in src/file_manipulator.py:

from commonforms import prepare_form

Since commonforms pulls in heavy native dependencies at import time, the API fails to even start — even if that functionality is not used.

Impact

• API cannot start in minimal environments
• CI / Docker builds can fail
• makes onboarding harder for new contributors

Possible fix

Move the import inside the function where it’s used (lazy import) and handle missing dependency with a clear error message.
