Send publicKey in RPC requests for implicit username claiming

Updated client to send publicKey in all authenticated RPC requests,
enabling server-side implicit username claiming.

Changes:
- Added publicKey field to RpcRequest interface
- Added publicKey to all authenticated RPC method calls
- Removed username claiming requirement from publishService()
- Auto-mark username as claimed after successful publish

Users no longer need to call claimUsername() before publishing
services. The server will automatically claim the username on
the first authenticated request.
