refactor: Refactor codebase by removing unused scripts and configurations

[Kanchan-Microsoft]

Purpose

This pull request updates documentation to reflect a migration from Azure Container Apps and Azure Container Registry to Azure App Service for hosting the application's web frontend and backend. It also updates related security guidance, quota and troubleshooting documentation, and deployment parameter descriptions. The most important changes are summarized below:

Resource and Deployment Documentation Updates:

• Replaced references to Azure Container Apps and Azure Container Registry with Azure App Service in both the main README.md and documents/DeploymentGuide.md, including updated descriptions, pricing, and links. [1] [2]
• Updated the list of customizable deployment parameters to remove container registry settings, reflecting the removal of Azure Container Registry as a required resource.

Security Guidance:

• Updated security recommendations to use Virtual Network integration and access restrictions for Azure App Service, replacing previous guidance for Azure Container Apps.

Troubleshooting and Quota Documentation:

• Removed troubleshooting entries related to Azure Container Apps limits and environment deletion, and added/updated guidance for Azure App Service capacity and related errors in documents/TroubleShootingSteps.md. [1] [2]

These updates ensure the documentation accurately reflects the new hosting architecture and provides relevant guidance for deployment, security, and troubleshooting.

Does this introduce a breaking change?

• Yes
• No

Changes:

• Removed legacy Container Apps infrastructure templates/modules (infra/resources.bicep, infra/modules/fetch-container-image.bicep) and related naming data (infra/abbreviations.json).
• Regenerated/updated compiled ARM template output (infra/main.json) and made small infra template refactors/comments.
