Convert assets in the assets pallet to ERC20 precompile addresses
Correct Pattern for Paseo Asset Hub:
Format: 0x + assetId (8 chars) + zeros (24 chars) + 01200000
The 0x120 suffix indicates a Trust Backed Asset prefix on Polkadot Hub Testnet.
Example: Asset ID 50000281 → 0x02Faf19900000000000000000000000001200000
