Fix auth guidance: update tab name, add Azure CLI prereq, fix shared include for VS Code

- Rename tab from 'DefaultAzureCredential' to 'ActiveDirectoryDefault' (correct terminology)
- Add Azure CLI to prerequisites (required for ActiveDirectoryDefault auth)
- Update shared include: fix outdated VS Code guidance (Azure Account extension deprecated)
- Update 'Azure AD' to 'Microsoft Entra' branding
- Fix 'sign-in' to 'sign in' per MS Style Guide
