util: introduce TrySub to prevent unsigned underflow 
Introduce `TrySub(T&, U)` which subtracts an unsigned integral `U` from an unsigned integral `T`, returning `false` on underflow.
Use with `Assume(TrySub(...))` at coins cache accounting decrement sites so invariant violations fail immediately rather than silently wrapping.
