fixed inability to create new entry inpack_dispatch table when changing non-duration followup option to duration one; activated changes to pack overdue table - calculates deltas on return_due date rather than pack_sent; patched outreach/haematology.tt sysmex data calculations to correctly handle *000 values; reversed attempt to share get_auto_requested_lab_tests methods - too complex as crons can't use DB classes

patched diagnosis_confirmation_required() to accept list of lab-tests from diagnosis_confirm.yml config

refactored L::Utils::get_yaml to only require args needed for construction of path/to/yaml_dir/filename to remove duplication from components requiring a get_yaml_file() method (Controllers, Model & ScriptHelpers)

moved diagnosis_confirmation_required from Local::Utils to new Local::Role::DiagnosisConfirm - didn't belong in Utils class, and function now needs to access LIMS config to load yaml files dir dynamically depending on CENTRE env param
