Jamie Pine 91b6808c5e refactor: remove unused StateSyncHandler dead code
The StateSyncHandler was a leftover from an earlier architecture where
protocol handlers were meant to be separate. The current implementation
bypasses it entirely by having the network protocol handler directly
call PeerSync::get_device_state() which properly uses the registry.

Backfill has been working fine because it completely avoids this code path.

Changes:
- Remove StateSyncHandler struct and all its methods from protocol_handler.rs
- Remove state_handler field from BackfillManager
- Update exports in mod.rs
- Clean up imports in backfill.rs

This eliminates the confusing TODO comments about serialization that
were already implemented elsewhere.
