can re-screen reported requests - new test generation suppressed; molecular worksheets configured to skip requests defined in yaml config; incomplete gallium datafile edits
bugfixes: C::Local::Worklist::pcr_worksheet() only interested in [dr]na_extraction test_name; extraction and pcr worklists split samples into separate rows
put CSRF logic into histology blocks worklist to prevent form resubmission - had multiple duplicate 'returned blocks' entries in request_lab_test_history
histology block refs displayed in year groups; changed date ref to 16 char string for recorded delivery info; returned list of records updated instead of redirect to redisplay block ref worklist
