Caesar layout: _paginate_and_confirm behaves incorrectly, bypassing transaction confirmation

[coderabbitai]

Description

The device test helper _paginate_and_confirm does not work correctly on the Caesar layout when confirming transactions (observed during Tron TRX transfer flow in PR #6883).

Observed behavior

• The test T3B1_en-device_tests-tron-test_sign_tx.py::test_sign_tx[TransferContract] ends inside the info context menu instead of completing the confirmation flow.
• _paginate_and_confirm enters the menu via an unexpected swipe_up() call.
• After iterating all menu items, it calls press_yes(), which bypasses the entire layout and returns without actually confirming the transaction.

Expected behavior

_paginate_and_confirm should paginate through the content and complete the confirmation flow — not terminate inside the info context menu.

Additional context

• The same issue was previously encountered in Support chunked addresses in SignTX flow for Solana #6545, which stalled because of it.
• Reported by @obrusvit during review of Tron: Improve Transfer flow #6883.
• Requested to be tracked by @PrisionMike.
