️🛠 - Add ethereum confirmed blocks property and derive confirmed state from it

[Tuditi]

Task description

We need to distinguish confirmed/non-confirmed blocks on Ethereum. To become confirmed a transaction must have a threshold confirmed blocks (e.g. 6) after its own block. Therefor we need to have the same behavior as on L1

Pending Activity contains a property of e.g. 2/6 confirmations, where 2 is the amount of confirmed blocks and 6 the threshold. Confirmed Activity contains just a text that states confirmed

Add a pill with confirmed/unconfirmed
