RfC672 - fix inaccurate turnaround times stats & audit function for samples with a significant number of unauthorised requests, eg RXPB and where date restriction set close to current date

RfC524 - change PNH screening terms; fix error in ncg_pnh.pl HTS count query - incorrect 'group by' with COUNT(*)

Fix teaching cases query for NBT (no authorisation stage)

Trend analysis charts - avoid division-by-zero error if total is zero (eg when lab-test renamed)

fix broken trend analysis following updated FISH result options

adapt turnaround times audit for NBT (don't use authorisation)

refactored report_notification block for improved clarity; permitted designation now defined in config files; allows user to set notifications inactive

syntax bugfix; new seachable field Patient Notes

retired 'Outreach' screening term and replaced with separate outreach categories (ready to switch off auto-screening Outreach); stopped retrieveing outreach data in C::Report::outreach as it's (re)fetched in downstream load() function; defined pnh, hiv, outreach & molecular screening terms as global vars in Model::Audit - easier to amend categories; new simple SQL search field Request Notes

adjusted trend analysis chart x-axis display and duration

combined trend_analysis config data from C::Chart & M::Audit into yml file for simplicity of maintenance and extension

new audit function 'trend analysis' - requires ChartDirector v6 for rounded-corners

bugfix to nhs_number compliance audit - query required rquest to be in clinical trial - should be 'trial_name IS NULL OR trial_name NOT IN (..)'; added summary section to dashboard request status

adjusted M::Audit::_lab_test_data() to return timestamps instead of dates for lab_test_audit.pl script - does not affect lab test turnaround times resource

new lab-test audit script; moved common M::Audit::turnaround_times_lab_tests() functions into M::Audit::_lab_test_data() for share with new lab_test_turnaround_export() function; lab test turnaround times sets correct start time of tests auto-requested at registration (eg histology stains), previously assumed to be at screening; M::Roles::Query::_set_search_constraints() accepts DateTime objects for date_from & date_to params
