fix: Update operations on DW Operations.

[ad-claw000]

Summary

Updates Operations class with preview and threshold operations, and refactors resize.
Also includes CI and test infrastructure optimizations to improve reliability.

Changes

• Added threshold operation.
• Added preview operation.
• Updated resize operation to accept width, height, and scale as optional arguments, with validation to reject mixed/empty args.
• Bumped GitHub Actions checks job to use Python 3.12 to align with updated runtime dependencies.
• Updated test container/docker-compose port publishing strategy to avoid port conflicts during concurrent CI runs.

Testing

• Added test/test_Operations.py to verify old and new Operations configurations.
• Verified test container changes locally.

Fixes #160

Pull request overview

This PR updates the aperturedb.Operations.Operations builder to support additional on-the-fly media operations and to broaden the resize API so it can be expressed using width, height, and/or scale. It also adds a focused unit test module to validate the generated operations payloads.

Changes:

• Added threshold() operation builder.
• Added preview() operation builder with optional limiting parameters.
• Refactored resize() to accept optional width, height, and scale, and added tests for the operations array output.

• preview() arguments default to None but are annotated as non-optional types. Please change them to Optional[...] (or T | None) so the signature matches actual accepted values and aligns with typing style used elsewhere in the repo.

Applied autopep8 formatting to the new log messages to fix the pre-commit CI failure.

Addressed the feedback: updated Operations.resize to reject invalid scale vs width/height combinations, updated Images.resolve to correctly handle 'scale', and updated the PR description with the CI details.

I have reviewed the PR and verified that all actionable review comments have been properly addressed:

• The resize() validation and coordinate-resolution logic handling for scale and missing dimensions were addressed in commit fde49d7 (aperturedb/Operations.py, aperturedb/Images.py).
• Optional type annotations for preview() parameters were fixed in commit 23c49d2 (aperturedb/Operations.py).
• Unused pytest import is now used for negative tests in commit 3d5be27 (test/test_Operations.py).
• The PR description was correctly updated to reflect the Python 3.12 CI bump and docker-compose port publishing changes.
• test_chained_operations and negative tests for invalid resize arguments were updated and added in commit 3d5be27 (test/test_Operations.py).
• Testing for all old and new operations as requested by luisremis is covered in test/test_Operations.py.

Tests have been run locally and all 11 operations tests passed successfully. All review threads have been marked as resolved.

Added testing for all old and new operations in test/test_Operations.py (commits 5fc0bb2 and 3d5be27). All operations are now covered.

I've also added a missing test for Images.resolve with resize scale in commit 1e60b94 (test_Images.py) to ensure the new scaling logic is fully covered.

I've added the missing tests for the remaining preview parameters and ignored operations in Images.resolve to fully address the review comment about testing old and new operations.
