fix: Teams citation issue and add user to postgresdb

[Pavan-Microsoft]

Purpose

This pull request introduces support for a new environment variable, AZURE_APP_API_BASE_URL, across the Teams extension and deployment scripts to enable API-based file access in Microsoft Teams. It also updates the infrastructure and provisioning scripts to grant database and schema-level permissions to a specified principal in PostgreSQL, improving security and access control. The documentation and sample environment files are updated to reflect these changes.

Teams Extension and API Integration:

• Added support for the AZURE_APP_API_BASE_URL environment variable throughout the Teams extension (config.ts, .env files, Bicep templates, and deployment YAMLs), enabling API-based file access for Teams cards and bots. [1] [2] [3] [4] [5] [6] [7] [8] [9]
• Updated the Teams card builder logic to use the new API endpoint for file access when generating card actions. [1] [2]

Documentation and Configuration:

• Updated docs/teams_extension.md and sample .env files to document the new environment variable and clarify setup instructions for Teams extension deployment. [1] [2] [3] [4]

Infrastructure and Provisioning:

• Modified Bicep and JSON ARM templates to propagate the new AZURE_APP_API_BASE_URL variable and update resource dependencies for improved deployment reliability. [1] [2] [3] [4] [5]

Database Security and Automation:

• Enhanced the PostgreSQL table creation script and deployment logic to accept a principal ID, automatically create the principal if needed, and grant database/schema permissions for secure access. [1] [2] [3] [4] [5]

DevOps and Local Development:

• Added a step to enable service principal creation in local provisioning scripts and clarified comments for multitenant app support. [1] [2]
