Extract a common list item component with outline variant as we use them
in several places in dapp. We can't add a new variant using chakra
theming because the `ListItem` is a part of the `List` component and
does not have separate theme. In that case we should pass the eg
`variant="otuline"` to the `List` component but in my opinion does not
fit here because list can be order or unordered.

Take into account the tBTC v2 token total supply. Also here we fix unit
test for this hook.

And display data in component.

To use some tBTC stats in other places in T dapp.

Display tBTC stats as an empty state if user is not connected with a
wallet.

We want to redirect users to transaction details in the blockexplorer.

`DefaultProtocolHistory` -> `ProtocolHistory`

Clarify in comment that the `timestamp` field is in seconds.

We should write `TBTC` (started with capital `T`) when it's in the
middle of the word that is writtne in camelCase convention. Everywhere
else we should stick to `tBTC`.

`TBTCBrdigeStats` -> `TBTCBridgeStats`
