feat(tests): reserve balance violation reverting with its call frame

[pdobacz]

Covers the debiting frame and its enclosing frame unwinding, against the frame returning normally.

I've just realized we don't have an explicit test for this case (we have one in the MIP-4 family, but not here, where it belonged).

Greptile Summary

Adds explicit conformance coverage for reserve-balance violations across nested call-frame rollback behavior.

• Exercises normal exits through STOP and RETURN.
• Exercises reverted or exceptional exits through REVERT and INVALID.
• Verifies behavior both with and without an enclosing frame reverting.
• Checks transaction storage rollback and final account balances.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness or security issues identified.

The expected storage and balance states consistently reflect whether the delegated EOA’s value debit survives its call frames and therefore triggers transaction-level reserve-balance rollback.
