Create a "transaction confirmation" page, so climbers can show to the gym as proof

Is your feature request related to a problem? Please describe.

Right now, the pass transaction is an informal process where people tell each other their contact details for the pass trades. This may create loopholes and gyms may or may not have a process to accommodate this.

Describe the solution you'd like

I would like to suggest a "transaction confirmation" page. Upon agreement of a sale, or amount paid, seller can "confirm" the trade and buyer may then show to the gym. The page should contain necessary info the gym needs for sharing pass, validity time, and who's and who's.

e.g.:

Dear Kinetics,
On Nov 26 Wei (phone number) would like to share her pass with Jill (phone number).

(with some pleasant UI la)

Describe alternatives you've considered

NA

Additional context

We will also need to let the gyms know of this initiatives and have their acknowledgement to only check people in when they see this page.
