Input for strict barcode info

Happy to commit this if someone more familiar with strict barcode would like to review & signoff.

Noting that one of the commits changes the line endings from Unix-style to DOS-style. This gets in the way of reviewing the changes.

Regarding the substance, I would suggest wording along the lines of:

• The 'Strict Barcode' checkbox can appear next to barcode inputs on the checkout, checkin, renewal, and offline circulation pages.
• If checked, it will examine the barcode value to see if it contains only digits and meets the "Mod10" checkdigit algorithm. This checkdigit algorithm is often used by library barcodes that use the "Codabar" symbology.
• If the barcode does not meet the conditions, a "bad barcode" alert will be displayed. Staff are given the option to accept and continue using the barcode as input.
• "Strict Barcode" is only useful for libraries whose barcodes use the Mod10 checkdigit algorithm. However, several other checkdigit algorithms and symbologies are in use by libraries.

(I also note that it does not check whether the barcode is exactly 14 digits long)

Committed to main & picked back to rel_3_10.

Thanks, Gina & Galen!
