Render wallet and account name if the recipient is an imported account,
else render the truncated wallet address if the recipient is an external
account. We also introduced some refactoring to make us scale the
`QuestDetailsCard` by extracting UI and business logic to separate
components.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Extracts the recipient row from QuoteDetailsCard into a dedicated
component powered by a new hook to display wallet/account names or a
shortened external address, and updates tests/snapshots.
>
> - **Bridge UI**:
> - **Recipient Row**: Replaces inline recipient logic in
`QuoteDetailsCard` with `QuoteDetailsRecipientKeyValueRow`, which
navigates to the recipient selector and hides on swaps.
> - Displays `walletName / accountName` for internal accounts or a
shortened address for external recipients.
> - **Hooks**:
> - Adds `useRecipientDisplayData` (`hooks/useRecipientDisplayData`) to
derive `destinationDisplayName`, `destinationWalletName`, and
`destinationAccountAddress` using multichain selectors and feature flag.
> - **Styles**:
> - Adds `QuoteDetailsRecipientKeyValueRow.styles.ts` for layout and
text truncation.
> - **Tests**:
> - Adds unit tests for `QuoteDetailsRecipientKeyValueRow` and
`useRecipientDisplayData`.
> - Updates `QuoteDetailsCard.test.tsx` mocks (multichain selectors) and
snapshots to reflect new recipient row structure.
