[Bug]: Activity - `Swap tokens` grayed out on empty activity list

### Describe the bug

Whenever we select an account with funds but no activity, if we go to the Activity page, we can see the message `Swap your first token today.`
and the button `Swap tokens`. However, this button is disabled in some networks, making our suggestion pointless.

I'm unsure if that is due to not supporting Swaps on that selected network, however this is not the case for Robinhood, where we do support Swaps, but the button is grayed out.
Furthermore, whenever I'm on another network (ie Linea), clicking Swap, leads to an Ethereum Mainnet swap page, meaning, we are not constructing that swap based on the filtered network, which makes it pointless to gray out the button in some ocasions.

### Expected behavior
Unsure which route do we want to go. Few possibilities:
- Enable the Swap button always, and land into the Swap on Ethereum page always
- Enable Swap button only on supported networks, landing on the Swap on that specific network tokens
- Remove the suggestion when (if) that button is grayed out, as it is pointless
