Describe the bug

When a user adds a new network (e.g., Polygon), the token list does not automatically refresh. If the user immediately navigates to Swap → Token Picker, the token list stays in an infinite loading state because asset data has not yet been populated.

Only after the user manually changes the network filter on the main page (which refreshes asset data) does the token list load properly in the swap flow.

Happens on both Chrome and Firefox

Expected behavior

•	After adding a new network (e.g., Polygon), asset data should refresh automatically.
•	The refreshed asset data should make the tokens immediately available in the swap token picker.

Actual behavior

•	Adding a new network and going straight to Swap → Token Picker results in infinite loading.
•	Tokens only appear if the user manually triggers a refresh via the main page filter.

5.	Return to Swap → Token Picker.
6.	Observe that tokens now load correctly.
