[Monetization flow]

Content Script

1. Setup MutationObserver to detect link tags
2. For each found tag check if the href has a valid JSON response (based on OP Spec)
3. For each valid tag save details (Wallet Address response - authServer, resourceServer etc ... + a unique identifier - uuidv4, w/e)
   in a map/array/something and send START_MONETIZATION (payload wallet JSON - opt requestId TBD) event to background script
4. Receicer for MONETIZATION_EVENT that will dispatch a MonetizationEvent to the link tag
5. Watch for document visibility change
   • on hidden, stop monetization
     • send "STOP_MONETIZATION" event with payload requestId
   • on visible, resume monetization
     • send "RESUME_MONETIZATION" event with payload requestId

Background
4. In background - call monetizationServer.start()
4.1 request incoming payment grant
4.2 create incoming payment - NO AMOUNT
4.3 try to send payment - if received status code is 403, rotate token
4.4 revoke grant after creating incoming payment
4.5 add incoming payment details to a map - (key: tabId, value: {"uuidv4" : { ...incomingPaymentDetails, active: true }, ...})
5. Create quote with receiveAmount = RATE_OF_PAY / 3600 to incoming payment (active: true)
6. Create outgoing payment with quote identifier (active: true)
7. Send "MONETIZATION_EVENT" to content script with MonetizationEvent payload + request id
8. Watch for document visibility change

• on hidden, stop monetization
  • receive "STOP_MONETIZATION" event with payload requestId and mark active false for that requestId
• on visible, resume monetization
  • receive "RESUME_MONETIZATION" event with payload requestId and mark active true for that requestId
  • repeat steps 5-6 - if IP expired, go back to 4.1 and update payment details instead of adding a new record

9. Add tab listener to watch for closed tabs and remove payment details from map (step 4.5) for that specific tab
