N+1 API queries in prescription administration table

[rithviknishad]

Currently, the code flow in fetching data for the prescription administration table is:

1. List prescriptions for a consultation.
2. Computing the overall start and end administration date range to initialize pagination
3. Compute the latest range required to be shown in view (eg. last X hours)
4. Listing administrations for each of the prescriptions within that range.
