minor change to M::Audit::_get_post_screen_lab_test_requests() handling of empty @ array

patched charts & audit functions to handle minimal datasets eg UCLH not using tissue samples, and having empty dataset using date restriction

added function to edit request diagnosis error via audit resource

added lab-tests signed-off to Resources audit section; added results summary updates to ppm & results server feed; results summary textbox & select entries joined by new-line not semi-colon

standardised all Model classes using Moose to read 'extends' then 'with'; moved M::R::ReportUpdate::_do_additional_tests to M::R::LabTest::Update::auto_request_additional_tests() for sharing with M::R::ResultsUpdate::do_results_summary_update() so result summary input can auto-request new lab tests - required reconfiguration of additional_tests.yml; changed order of result summary drop-down and textbox entries when joined to form single string

replaced loading of Local::DBIxSimple in individual model classes with single loading in Model::Base; renamed DBIxSimple::get_meta to dbix_get_meta to avoid clash with Model::Base::get_meta (now renamed get_meta_data); fixed report.t - new method report_diff replaced comment

logic to determine whether to set request status to complete considers result summary datetime relative to authorisation datetime; replaced io unlink() with system unlink in render_pdf - was giving occasional errors; replaced M::Base::does_authorisation method with Moose attr to save repeat db queries; fixed oversight in _archive_report_details() causing history log to record amended specimen_date at every authorisation; gallium_data.pl checks for comment field to prevent fatal error; more report_status.t tests to test for status change on delayed result summary entry

moved report footer to configurable item; lab-test turnaround times includes test auto-requested at diagnosis

lab test turnaround times audit function

make_pdf() function loads logo from config file; changed method of loading local report template to use config setting

added ability to download turnaround times data
