feat: ✨ Add datahaven native transfer precompile (#309) 
## DataHaven Native Transfer Precompile

Implements EVM precompile at address
`0x00000000000000000000000000000007F5` (2073) to expose
`pallet-datahaven-native-transfer` functionality to the EVM layer.

### Features
- **Transfer to Ethereum**: Locks native tokens and sends them via
Snowbridge to Ethereum addresses
- **Pause/Unpause**: Admin controls to halt/resume transfers
- **View Functions**: Query paused state, total locked balance, and
sovereign account address

### Implementation
- Precompile using `#[precompile_utils::precompile]` macro with proper
gas accounting
- 15+ test cases covering success/failure scenarios
- Solidity interface with NatSpec documentation for contract integration

Enables seamless cross-chain transfers of DataHaven native tokens to
Ethereum L1.
