chore: remove unused signatures package

[harry-anderson]

Summary

Removes the core/services/signatures/ directory tree which contains unused code:

• ethschnorr - Schnorr signature implementation
• ethdss - Distributed Schnorr Signature protocol
• cryptotest - Test utilities for the above

These packages are not imported by any production code. Both ethschnorr and ethdss carry explicit XXX: Do not use in production until this code has been audited warnings and have never been integrated into any active code path.

Test plan

• CI passes (no compilation errors from removed imports)
• Confirmed via grep that no package outside core/services/signatures/ imports any of these packages
