Allow Bids on User Collection

[Mike-E-angelo]

Related to #42 but this feature will also apply to licenses found within a collector's collection (seen from the Collector's Catalog).

We want to enable the ability for another collector to make a bid on an existing piece. This is a high-value action as it not only facilitates value but it totally adds a social network quality to the system. We have this planned with the license explorer (#42) but it can be applied here too.

• When a collector makes a bid, they must have the funds they are making the bid with. If they have sufficient funds, the funds are held on a system hold for 24 hours.
• Once the bid is made, it cannot be cancelled until 24 hours has passed (need to make this clear in the interface)
• Maybe once we get this done, we could allow others to make counterbids?
• Future version will allow collectors to say if they will allow bids or not -- on entire collection and on individual pieces

Maybe allow this for primary issuance as well? 🤔
