feat: cobb angle with cstools

[laura-borghesi-lum00n]

This pull request introduces the Cobb Angle measurement tool to the imaging toolkit and updates the documentation to describe its usage. It also includes a patch version bump to reflect these feature additions.

Cobb Angle Tool Integration:

• Added CobbAngleTool import and registered it in the dvTools object in imaging/tools/default.ts, enabling its use as a measurement tool. [1] [2]
• Added a CobbAngle entry to the DEFAULT_TOOLS configuration, specifying its properties, options, and description for annotation purposes.

Documentation Updates:

• Updated docs/examples/defaultTools.html to display instructions and information when the Cobb Angle tool is selected, describing its purpose and usage.

Other Changes:

• Incremented the package version in package.json from 3.8.11 to 3.8.12 to reflect the new feature.
• Minor UI improvement in docs/examples/base.html to ensure the loading spinner is hidden after all files are processed.

Code Review

This pull request introduces a new CobbAngle tool for measuring angles in medical imaging, including its implementation and registration in the default tools configuration. The review identified several issues regarding state management and coordinate handling. Specifically, the reviewer suggested refactoring the tool to query the cornerstone tool state directly instead of using class-level flags to avoid synchronization risks, and recommended updating the coordinate conversion logic in the distance calculation helper to ensure accuracy. Additionally, the reviewer proposed cleaning up temporary drag state properties by moving them into local scopes within callback functions.
