fix: merging dev changes to main

[Roopan-Microsoft]

Purpose

• This pull request updates authentication configuration for the Web Application to improve clarity and ensure correct environment variable setup for Microsoft Entra ID integration. The changes primarily enhance documentation and infrastructure configuration to support proper authentication flows.

Documentation improvements:

• Added instructions to copy the Tenant Id during app registration and clarified its use for the APP_MSAL_AUTH_AUTHORITY environment variable in docs/ConfigureAppAuthentication.md.
• Updated the environment variable table in docs/ConfigureAppAuthentication.md to explicitly note how to set REACT_APP_MSAL_AUTH_AUTHORITY using the Tenant Id, and added the ENABLE_AUTH variable for clarity.

Infrastructure configuration:

• Added REACT_APP_MSAL_POST_REDIRECT_URL and REACT_APP_MSAL_REDIRECT_URL environment variables to the container app frontend module in infra/main.bicep to support authentication redirects.
