fix(azure): Add security properties to ARM template for policy compliance (#1023)

Added required security properties to fix Azure policy violations:
- Storage account: supportsHttpsTrafficOnly and allowBlobPublicAccess
- Function app: httpsOnly property

These changes ensure compliance with storage-secure-transfer, storage-no-anonymous, and functionapp-https policies.
