Feat/backend/deep user based analytics

[waveyboym]

Description

This pr aims to introduce analytics endpoints to the system. These will allow a user to make queries with time ranges for various things about a specific worker or all the workers in the office space. We have thus introduced these features in this pr:

1. user hours and all worker hours
2. user average hours and all worker average hours
3. user work ratio and all workers work ratio
4. user peak office hours and all worker peak office hours
5. user average office arrival and departure times and all workers as well
6. user in office rate and all workers too
7. most active employee(in terms of hours spent at work)
8. least active employee(in terms of hours spent at work)

We also added another final endpoint which just allows a user to toggle their onsite status between on site and off site at any time of the day(between office hours) and lastly to toggle their status not once but literally an infinite amount of times in a day(so long as it is between office hours).
