Integrate "Events" more deeply into Unchained

[pozylon]

Definitions:

• With an order somebody can buy virtual products
• Virtual Products (=Token): A Token could be any kind of NFT or a Ticket to a Concert

Invalidation:

Pre-defined validity ranges for "redeemability":

• Case 1 Coupon or License Key: Valid until 01.05.2025
• Case 2 Event: From 01.05.2025 15:00 - 01.05.2025 23:00
  we can't know for sure how a case considers if a ticket is redeemable, it could be based on some external state.
• A user could loose access to a ticket because maybe the owner changed

A user could loose access to a ticket because maybe the owner changed, in such a case we'll need to be able to find out if that happened n a UI.

• Token should have optional expiryDate
• Token should have optional isInvalidateable()
• Token should have optional invalidatedDate
• Unchained should support creation of a "token access key" for a specific token that can be used for a barcode, that token access key should be returned in the Token type
• Unchained should support invalidate token mutation
• Unchained should support Order.tokens to show the tokens that got "materialized" with a specific Order

Reporting:

When TokenizedProduct resembles an Event and invalidation resembles Scanning of the ticket at the entrance, a common case for events is seeing reporting data:

Show / No-Show List for an Event:

• Total supply and total emitted tokens
• Invalidated vs Un-Invalidated tokens

Revenue Report:

• Show all confirmed/fullfilled orders in a certain time range with delivery/items/payment/discounts/tax & gross total
• Show all order positions of orders from above in a certain time range with "unit price"/price/discount/tax & gross total
• Show the above list filtered by a product in a certain time range

Ticketing Experience:

Currently, generating the ticket as PDF and integration into Apple Wallet and Google Wallet have been done in userbase code of a customer, including Pass Notifications. Unchained should deliver these plugins out-of-the-box in Open-Source code and also have a proper default design for PDF tickets:

• Port additional logic from the Theater im Hof to the default ERC721 Warehousing Plugin (eth-minter.ts)
• Warehousing Director should support "invalidation" hook to regenerate the metadata based on updated information
• Add Apple Wallet Plugin and document how to configure
• Add Google Wallet Plugin and document how to configure
• Add an HTTP handler that can generate the appropriate apple wallet and/or google wallet pass with the ticket id and the "token access key"
• Add an HTTP handler that can generate a print-pdf of a ticket with the ticket id and the "token access key"
• Add a template Order Confirmation Message that attaches all the tickets as PDF's, a .pkpasses container and shows the appropriate add to google wallet link if possible.
