This change refactors the regular expression handling for Batch Item Modification, MARC Modification templates, and Callnumber splitting. It moves from Perl's traditional compile-time regular expression handling to a more dynamic (but restrictive) run-time regular expression handling more similar to Python's "sub" regex method. This functions to reduce vulnerabilities to code injection into Koha's Perl backend.
This fixes an accessibility issue on the patron's OPAC account messaging preferences form: Missing legend for the fieldset with submit changes and cancel buttons.
It adds a legend tag "visible" for screen reader patrons so that it is clear for the group of buttons what they are being asked to do.

42395 Missing translations for the existing holds table (load_patron_holds_table) for a record in the staff interface
This fixes the translatability of strings for the existing holds table in the staff interface for a record (Staff interface > [details page for a record] > Holds > Existing holds).
These strings were not previously translated:
- Priority column: In transit, Waiting, and In processing
- Change priority column: tooltip text for arrows: . Move hold up . Move hold to top . Move hold to bottom . Move hold down

This fixes the "Add guarantor" pop-up window when adding a guarantor for a patron.
The form was populating the "Sort 2" field with the value from the patron you are adding the guarantor to (if they had values stored for the Sort 1 and Sort 2 fields in the library management section).
This fixes the capitalization (title case to sentence case) for a heading in the "Point of sale payout receipt (PAYOUT)" print notice template: Refund Payout Receipt --> Refund payout receipt.
Note: This only affects new Koha installations. Existing installations need to either manually update the notice or replace the existing notice with the default notice text.
42695 Minor language and markup corrections to reports error messages
This fixes the HTML markup for some report error messages, along with some minor text changes:
- Uses an H1 for the heading
- Uses p for paragraphs
