ci: Execute workflows only when relevant files updated

[AjitPadhi-Microsoft]

Purpose

• This pull request updates the workflow triggers in several GitHub Actions configuration files to use the paths filter. This ensures that workflows only run when relevant files are changed, improving CI efficiency and reducing unnecessary runs.

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.

What to Check

Verify that the following are valid

• I have built and tested the code locally and in a deployed app
• For frontend changes, I have pulled the latest code from main, built the frontend, and committed all static files.
• This is a change for all users of this app. No code or asset is specific to my use case or my organization.

Pull request overview

This PR adds path filtering to GitHub Actions workflows to optimize CI/CD execution by running workflows only when relevant files are modified. The changes aim to reduce unnecessary workflow runs and conserve CI/CD resources by triggering workflows based on file patterns rather than running on every commit.

• Adds path filters to Python testing and linting workflows to run only when Python source files, requirements, or tests change
• Configures Node.js build workflow to trigger only on frontend file changes (TypeScript, JavaScript, CSS, HTML, etc.)
• Implements path filtering for Docker build workflow to run when source code, frontend files, or Dockerfiles are modified
• Updates deployment workflow to trigger based on application code, infrastructure files, and configuration changes
• Removes the deprecated deploy-v2.yml workflow file (853 lines deleted)
