🔒 Security Fix: Addressed RumpelGuard vulnerability preventing transaction selector bypass

• Fixed: Implemented check to prevent malformed function selectors (length > 0 and < 4 bytes) that could bypass security restrictions, while preserving functionality for ETH transfers (0-length data)
• Verified: The issue has already been patched in the rumpel-wallet repository in commit 65ed6481, which includes comprehensive tests for both disallowing small data payloads and allowing proper ETH transfers

This addresses the Low Risk vulnerability where external protocols could potentially force the Rumpel wallet to execute unauthorized functions through malformed calls.
