Explorer: Transaction viewer (pt2)

[anxolin]

Description

Follow up to gnosis/gp-ui#780

While on that task a Tx/batch details view was added, on this task the goal is to show a list of txs

Additional resources

Design should be similar to Orders table, and not very far from Agustin's initial proposal gnosis/gp-ui#780 (comment)

Except that the columns will not include order fields, but instead whatever can be fetched from the chain for each tx, such as:

• Tx time (derived from block time)
• Gas related info (minimum gas, gas price, etc)
• Whatever else might be relevant (the solver which submitted the tx)

Feature breakdown
It depends on:

• Network switcher Add a new page to create a valid App Data document #160
• Contracts network aware Handle error when Barn is down #408

It includes:

• Design txs page
• Implement component as storybook
• Implement handlers/hooks/api (whatever is relevant) to fetch contract events
• Wire up component and logic
• Pagination
• Update list on every new block (only if on the first page)

Good to have:
