fix(bridge): normalize Polygon native token addresses cp-7.75.0 (#29440)

<!--
Please submit this PR as a draft initially.

Do not mark it as "Ready for review" until this PR meets the canonical
Definition of Ready For Review in `docs/readme/ready-for-review.md`.

In short: the template must be materially complete (not just section
titles
present), all status checks must be currently passing, and the only
expected
follow-up commits must be reviewer-driven.
-->

## **Description**

<!--
Write a short description of the changes included in this pull request,
also include relevant motivation and context. Have in mind the following
questions:
1. What is the reason for the change?
2. What is the improvement/solution?
-->

Polygon native POL can enter the bridge/swaps flow from token details
with Polygon's native token alias address
(`0x0000000000000000000000000000000000001010`). Bridge state expects
native EVM assets to use the swaps native zero address, so the alias can
break downstream balance, gas, and quote matching behavior.

This change normalizes source and destination bridge tokens as they are
stored in the bridge Redux slice. That keeps bridge state canonical for
all callers of `setSourceToken` and `setDestToken`, including the POL
token details swap entry point.

## **Changelog**

<!--
If this PR is not End-User-Facing and should not show up in the
CHANGELOG, you can choose to either:
1. Write `CHANGELOG entry: null`
2. Label with `no-changelog`

If this PR is End-User-Facing, please write a short User-Facing
description in the past tense like:
`CHANGELOG entry: Added a new tab for users to see their NFTs`
`CHANGELOG entry: Fixed a bug that was causing some NFTs to flicker`

(This helps the Release Engineer do their job more quickly and
accurately)
-->

CHANGELOG entry: Fixed a bug that prevented quotes when swapping from
POL token details

## **Related issues**

Issue: #29231

## **Manual testing steps**

```gherkin
Feature: POL swap quotes from token details

  Scenario: User starts a swap from the POL asset details screen
    Given the user has POL on Polygon Mainnet
    And the user opens POL from the wallet token list
    When the user taps Swap from the POL token details screen
    And the user enters a valid POL amount
    Then the swap flow fetches and displays available quotes
```

Unchecked boxes are ambiguous: they are not an implicit "N/A" and they
are not
a silent "skip". See `docs/readme/ready-for-review.md` for the full
