fix: hash approval errors + return txHash

[iamacook]

What it solves

approveHash error notifications, as well as returning txHash.

How this PR fixes it

Relative to the legacy processTransaction error handling, contract errors occuring from approveHash are now displayed in a notification.

A few type changes were made here in order to simplify the error handling as well.

The txHash is also returned here as owner addition/editing checks that the txHash exists in order to update the address book.
