fix(caesar): don't omit description in confirm_value

... when info_items is non-empty.

This fixes an issue in Ripple confirm_account_deletion where the
fee limit is shown without any description and multiple similar
issues in Stellar payment-like operations (which internally use
confirm_stellar_output_amount).

The short version

What changed, and why it matters

This commit fixes a display bug in Trezor hardware wallets running the 'Caesar' user interface. In certain Ripple and Stellar transaction confirmation screens, a helpful description label (for example, explaining that a shown number is a fee limit or payment amount) was accidentally left off. The fix makes sure the description appears alongside the value, so users are less likely to misread what they are approving. It is a user-interface clarity issue rather than a direct theft-of-funds vulnerability, but it could contribute to a user approving a transaction they do not fully understand.

Recommended action

Treat as a low-severity UI/UX fix. No emergency response is needed, but ensure the fix is included in the next firmware release so users see complete transaction descriptions before signing. Review other layouts for similar subtitle/description omission patterns.
