fix(drive): use RootTree enum instead of magic number 72u8

[QuantumExplorer]

Issue being fixed or feature implemented

The ShieldFromAssetLock proof query hardcoded 72u8 for the SpentAssetLockTransactions root tree path. If the enum value ever changes, this would silently break.

What was done?

Replaced vec![72u8] with vec![RootTree::SpentAssetLockTransactions as u8].

How Has This Been Tested?

• cargo check -p drive — compiles cleanly

Breaking Changes

None.
