Wrap fiat value in parens on Stake amount tile

[j0ntz]

Description

Asana task

The Stake/Unstake/Claim amount row (EditableAmountTile) rendered the fiat
value raw, right after the crypto amount, with no surrounding brackets.
Its compressed render branch and the sibling CryptoFiatAmountTile
(used on the Earn overview list) already wrap fiat text in parens; the
default (non-compressed) branch was the one instance still missing it.
Wrapped it to match.

The exact "staked / earned / unstaked" overview rows from the original
repro (CryptoFiatAmountTile on the Earn overview scene) were already
fixed on develop by an unrelated refactor (bbd3259a6, 2025-10-17,
predates this branch) — no change needed there.

Overview
Stake/Unstake/Claim amount rows use EditableAmountTile. The default layout showed the fiat equivalent next to the crypto amount without parentheses, while the compressed branch and CryptoFiatAmountTile already used (fiat).

The default branch now renders fiat as (${fiatAmountSyntax}), aligned with those patterns. Fiat text is only built when fiatAmount !== '' (instead of a truthy check). The component is typed as React.FC. CHANGELOG and Send scene snapshots are updated.
