[Maintenance] - Calendar Action Needed

Description

A place on the calendar page where it shows what meetings your attendance has been requested at or what availability you need to fill out, ive gotten like 12 requests and since I can't fill it out on mobile i come back and theres a bunch of meetings I need to confirm availability for and I need to go find them all in slack which is lowkey annoying, this may already exist but I don't know where it is.

We should implement a filter for the calendar where a user is able to see events where they have an action that needs to be done (ie if they need to confirm their availability / schedule the event if they are creator).

Acceptance Criteria

• new tab on the calendar that shows items where actions are required

Proposed Solution

• create a calendar util that takes in an event and user id and returns one of:
  • CONFIRM_AVAILABILITY (you're in requiredMembers, not in confirmedMembers, event status = UNCONFIRMED)
  • SCHEDULE_EVENT (you are the creator of the event, event status = CONFIRMED),
  • null
• add a new tab to the calendar to display the action needed items
• reuse the existing EventClickPopup on this page so it links to the same page as it would clicking on the calendar

Mocks

No response

Start at the calendar page and inspect the existing EventClickPopup and event data fields. Add an action-needed tab that identifies CONFIRM_AVAILABILITY and SCHEDULE_EVENT cases for the current user, reuses EventClickPopup, and verify that the listed items link to the same destination as calendar events.
