End to end local Integration test for parseImage function: See issue #1

[gabrielbugarija]

NOTE: The Test is local, and without an AWS key and endpoint, spinup and spindown could not be implemented.

Overview
This PR adds an integration test suite for the parse_image(...) function. The tests are designed to run entirely on a local machine and simulate end-to-end image parsing behavior using either a real API or a mocked one.

Test Capabilities

• Uses local test images stored in the project directory
• Encodes images in base64 and sends simulated API POST requests
• Validates the structure and content of responses (e.g., checks for "segments")
• Supports mocked API behavior using unittest.mock
• Includes visual comparison of UI states using before/after screenshots
• These tests are self-contained and can run without any cloud or AWS dependency.

Requirements

• Make sure the following Python libraries are installed:
• pytest – for running tests
• Pillow (PIL) – for image handling
• requests – for HTTP requests
• unittest.mock – for mocking API responses
• Test image files placed in the same directory as the script

Updates are welcome :)

Thanks for the contribution, @gabrielbugarija ! Good initiative getting an end-to-end test running locally.

This isn't ready to merge for a few reasons:

• The test mocks out the actual parse_image logic, so it's not really exercising the integration path.
• The file should be placed under tests/, following the existing structure.
• The image diff logic using ImageChops is fragile and wouldn't hold up in more complex scenarios.
• The naming convention for the file (test_parseImage_local.py) doesn't follow standard Python or project conventions. Stick to lowercase with underscores, e.g. test_parse_image_integration.py.
• Hardcoding image paths and relying on manually-placed files isn't scalable. Use fixtures or temp files where possible.

Feel free to revise this PR or propose a different issue to tackle after exams. I appreciate the effort and am happy to review future contributions.
