More verbose proof display

[monsieurtanuki]

We recently changed the display of proof lists, from grid to list.

We therefore have more space, and can display more data, as on the website:

• type (receipt, price tag, ...)
• number of prices
• location
• date (that's the only data we used to display)
• currency
• timestamp

That new display would look like the price display (same kind of chips).

Could be extended to proof page, where displaying additional data would make sense.

• cf. Show price count in more places on proofs #6479

@monsieurtanuki ,
May I work on it?

Hi @AshutoshKhadse23! Sure!

Please reuse the chips already used for price list. I believe they're all available:

• number of prices
• location
• date (that's the only data we used to display)
• currency
• timestamp

Except "type", that doesn't exist I believe. For this one, just use a standard chip with the localized label.

@monsieurtanuki,
I know you are looking for a price button in the UI, but this other approach looks cleaner. What do you say?
Just let me know, I will create the PR accordingly.
