…nd stablecoins in QuickBuy sell receive list (TSA-642) (#31235)

## **Description**

In QuickBuy Sell mode the user sells the fixed position token and
chooses which token to **receive**. The Receive picker
(`useReceiveTokens`) only listed stablecoins (mUSD/USDC/USDT), so native
tokens were never offered.

This PR extends the Receive candidate set to always include the native
token of every chain already covered by the stablecoin candidates, so
natives and stablecoins are always visible regardless of balance.
Natives are built via the existing Bridge helper
`getNativeSourceToken(chainId)` and enriched through the same
`enrichTokenBalance` path (the `isNativeAddress` branch already handles
native balance/pricing), so no controller changes were needed.
Candidates are ordered stablecoin-before-native within each chain group
and the position chain is sorted first, which keeps a stablecoin as the
default selection (`sellDestTokenOptions[0]`).

## **Changelog**

CHANGELOG entry: Fixed QuickBuy sell flow so native tokens are always
shown alongside stablecoins in the "Receive" token list.

## **Manual testing steps**

```gherkin
Feature: QuickBuy sell receive token list

  Scenario: user opens the Receive picker when selling a position
    Given I am on a trader position and open QuickBuy
    And I switch to Sell mode
    When I open the "Receive" token picker
    Then the list shows the native token and stablecoins for each supported chain
    And the position chain's stablecoin is selected by default
    And tokens I do not hold still appear with a $0.00 balance
```

#### Performance checks (if applicable)

- [x] I've tested on Android
  - Ideally on a mid-range device; emulator is acceptable
- [x] I've tested with a power user scenario

to import wallets with many accounts and tokens
- [x] I've instrumented key operations with Sentry traces for production
performance metrics
- See [`trace()`](/app/util/trace.ts) for usage and

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> UI-only expansion of receive picker options using existing bridge
token helpers and enrichment; no auth or controller changes.
> 
> **Overview**
> QuickBuy **Sell** mode’s **Receive** picker now lists **native
tokens** (ETH, POL, etc.) in addition to stablecoins, fixing cases where
natives were never offered.
> 
> `useReceiveTokens` builds one native per chain already covered by
stablecoin candidates via `getNativeSourceToken`, merges them into the
picker list, and keeps **stablecoins before natives** within each chain
group so the default receive token (`sellDestTokenOptions[0]`) stays a
stablecoin. Non-stable ERC-20s like WETH remain excluded. Comments on
`QuickBuyReceiveScreen` were updated to describe stablecoin-or-native
receive options; behavior is unchanged aside from the expanded list from
the hook.
> 
> Tests cover natives in the list, zero-address natives, preferred-chain
ordering, and stablecoin-first within the preferred chain.
