fix: merging dev to main

[Roopan-Microsoft]

Purpose

• This pull request introduces several changes across multiple files, focusing on configuration updates, workflow optimizations, and resource naming standardization. The key updates include refining .flake8 exclusions, simplifying GitHub Actions workflows, implementing a comprehensive abbreviations system for Azure resource naming, and making adjustments to Azure Bicep templates for improved modularity and security.

Configuration Updates:

• Updated .flake8 configuration to exclude src/backend/tests from linting.

Workflow Optimizations:

• Simplified the template_validation_job in .github/workflows/azure-dev.yml by removing unnecessary steps, switching to environment variables (vars) for Azure credentials, and using the latest version of the template-validation-action.
• Enhanced the docker-build-and-push.yml workflow by introducing historical tagging for Docker images and modularizing the build steps for backend and frontend images using docker/build-push-action. [1] [2]

Resource Naming Standardization:

• Introduced a comprehensive abbreviations.json file to standardize Azure resource naming conventions across categories like AI, compute, databases, and networking.

Azure Bicep Template Improvements:

• Updated infra/deploy_ai_foundry.bicep to use the new abbreviations for resource names, switched authType from ApiKey to AAD for AI Hub authentication, and added role assignments for AI Developers. [1] [2] [3]
• Adjusted infra/deploy_keyvault.bicep to accept keyvaultName as a parameter, removed soft delete and purge protection options, and enabled RBAC authorization. [1] [2]
