fix: add missing test-shared dependency for feature-wallet-impl unit tests

RealTronTransactionServiceTest needed test-shared's Mockito helpers
(whenever/eq/any/argThat), but feature-wallet-impl never declared
testImplementation project(':test-shared') - every other module that uses
these helpers (feature-account-impl, runtime, common, etc.) already does.
Also pin two ambiguous-without-it type inferences (argThat's lambda param,
emptyMap's type args) explicitly rather than relying on the dependency fix
alone to un-cascade them.
