Describe the bug

Mobile still uses the Show incoming transactions preference with individual switches for each network.

This is unnecessary and misleading as transaction history for all supported networks is queried simultaneously in the TransactionController.

In addition, the current logic only enables transaction history if the incoming transaction toggle for the current global chain is enabled, even though the activity list can now show transactions spanning multiple popular networks.

Expected behavior

All the Show incoming transactions toggles are removed, and transaction history is enabled only using the basic functionality toggle as in extension.
