fix: address trust signal alerts to skip internal accounts cp-13.4.0

[AugmentedMode]

Description

This PR fixes a regression where internal wallet accounts were incorrectly flagged as suspicious by the trust signal system when sending transactions. The issue was that trust signal checks were being applied to internal accounts, causing false alerts when transferring between accounts owned by the user (or to the same account).

The solution introduces a check to skip trust signal evaluation for internal accounts.

Changelog

CHANGELOG entry: Fixed a bug where internal wallet accounts were incorrectly flagged as suspicious when sending transactions.
