new patient dataset for recent pack dispatch

replaced dummy request data with real data from HILIS4 so the 4 scenarios (new, screened, pack overdue and pack due in future) are available for demo

switched to custom database for project; imported data from hilis4 & outreach tables for dummy patients; _query uses wantarray for return context; patient details form submission jquery; patient_details.tt presentation edits

queries handled by SQL::Library; login function responds to user email address as username

fixed incomplete db schema

added db schema
