Overflows Not Set to Panic

[MaksymZavershynskyi]

Informational
Reported by a third party.

Description
The Rust release profile does not have overflow checks on by default. As a result, any overflows (e.g. addition, subtraction, etc.) will simply wrap, potentially creating an inconsistent state.

No scenarios could be found to trigger overflows in the fungible-token contract.

Recommendations
The release profile should be updated to panic on overflows, that is, to include overflow-checks = true .
