Epic: Replace orders

[anxolin]

Description

Allow users to replace existing orders

Additional resources

This feature involves allowing users to, in a single operation, cancel existing orders and replace it with a new one.

It also allows users to "replay" existing orders by pre-filing the UI with data for a previous order.

Feature breakdown
It includes:

• Adding to recent activity [1]
• Recreate order (Canceled / Filled) UI [5]
• Replace order (Pending) [10]
• Sign the order: Add meta-info to the order so backend ensures that only one of the orders are executed [2]
• Replacing/Replace logic for old pending: only for new [5]

Good to have:

• ???
