[Due for payment 2025-06-11] Fix the not found page on adhoc web builds

[mountiny]

Problem

Currently, our ad hoc builds on web do navigate user to not found page after signing in which is an issue if we want to test anything related to onboarding on the adhoc builds

Solution

Fix the logic for adhocs so we go to Inbox same as on Prod/ Staging after signing in
