fix: Refactor AI Foundry Deployment to Use Resource ID Instead of Name and RG

[UtkarshMishra-Microsoft]

Purpose

This update modifies Bicep templates and deployment scripts to replace separate AI_FOUNDRY_NAME and AI_FOUNDRY_RG_NAME parameters with a single AI_FOUNDRY_RESOURCE_ID.
Key changes include:

Updated Bicep outputs to provide aiFoundryId instead of name/RG.

Adjusted script arguments and environment variable fallbacks to use aif_resource_id.

Removed redundant Azure CLI calls for retrieving resource ID.

Improved cross-subscription compatibility and reduced complexity in deployment scripts.

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.
