ci: update workflows for v3 branches, enhance deployment automation, and refine test/lint triggers

[Harmanpreet-Microsoft]

Purpose

This pull request updates several GitHub Actions workflow files to trigger jobs more selectively based on file path changes. The main goal is to improve CI/CD efficiency by ensuring workflows only run when relevant files are modified. The changes affect workflows for CodeQL analysis, deployment validation, Docker builds, linting, and testing.

Workflow trigger improvements:

• Added paths filters to the push and pull_request triggers in .github/workflows/codeql.yml, so the CodeQL workflow only runs when relevant source code, tests, or the workflow file itself are changed.
• Added paths filters to the push and pull_request triggers in .github/workflows/deploy.yml, restricting deployment validation to infrastructure and workflow file changes.
• Added paths filters to the push and pull_request triggers in .github/workflows/docker-build-and-push.yml, so Docker builds only run when backend, frontend, server, or the workflow file changes. [1] [2]
• Added paths filters to the push and pull_request triggers in .github/workflows/pylint.yml, so linting runs only when backend Python files, requirements, or relevant config/workflow files change.
• Added paths filters to the push and pull_request triggers in .github/workflows/test.yml, so tests only run when backend, server, test files, or relevant config/workflow files are modified.

These changes help reduce unnecessary workflow runs, saving CI resources and speeding up feedback for relevant code changes.
