FE: Update patron notice policy: Multiples options for "Lost item fee(s) charged"

Purpose: Add two options to the configuration of the triggering of "Lost item fee(s) charged", to allow for overnight bundling.

NB: All other settings, that appear on the same browser page but are not mentioned below, should be unaffected by the below work, i.e. they should work like they did before this work.

NB2: The behaviour of the update Lost item fee(s) charged notice policy section, should be similar to the behaviour of the Loan due date/time notice policy section.
