chore(runway): cherry-pick fix: reset state to prevent stale quotes on token switch (#15626)

- fix: cp-7.47.0 reset state to prevent stale quotes on token switch
(#15571)

## **Description**

This PR ensures that the bridge feature resets the BridgeController
state when switching tokens, preventing stale quotes from persisting
after a token switch.

## **Related issues**

Fixes:
[MMS-2442](https://consensyssoftware.atlassian.net/browse/MMS-2442)

## **Manual testing steps**

1. Initiate a bridge transfer.
2. Switch the source and destination tokens.
3. Observe that the quote state is reset and no stale quotes are shown
and dest amount is not glitching.
