[SPIKE] Define technical approach for ending a CHECK IN session when operator closes browser or logs out of FOLIO

Split from CIRC-412.

As a library user, I want one email that includes all information and items from my library based on an action [listed below*] because I do not want to receive several emails or an email for each item.

In summary, notices are sent when a check in session ends, which includes:

• When FOLIO operator hits End Session on Check-In App Screen CIRC-412
• When a check in session times out due to inactivity CIRC-412
• When FOLIO operator closes browser, which closes the existing session
• When FOLIO operator logs out, which closes the existing session

Scenarios

Scenario 1 - If operator closes browser

• FOLIO operator opens check in screen
• Then scans Patron A's 10 items
• Then closes browser (notice is sent to Patron A)

Scenario 2 - If operator logs out

• FOLIO operator opens check in screen
• Then scans Patron A's 10 items
• Then logs out of FOLIO (notice is sent to Patron A)

Requirements

• Must support user-initiated loan notices (e.g. check in items in one session)
• No expectations of sending an email that includes multiple notice types (e.g. an email should not include loan info and request info)
• No expectations of sending an email that includes multiple templates
• Items may span different loan policies

Spike Deliverables

• Technical approach must address scenarios outlined in UICIRC-238 and https://docs.google.com/document/d/1OylEJ6eDx8h7PvuwBa2jKO4dKrgDjnQ4H13oXA57TnY/edit#heading=h.hbd6j2t3hjc9 (see Problem 1, 2, 3 tables) . Please add approach to JIRA as a comment and present to team for approval
• Generate or update user stories based on approved technical approach
• Identify dependencies
