Switch from Tauri backend to new Backend interface

Replace all usage of the old Tauri backend instance with the new unified IBackend interface, as returned from createBackend().

Update all affected services, dependency injections, and imports so they now adhere to the new backend abstraction. Remove references to tauri where possible, and update service constructors and API calls accordingly.
