(Field) Incident Report UI improvement - optional field for IMS number

[virtual256]

Frequently, experienced Rangers will stop by the Operator shack to get the relevant IMS number for their Field Incident Report. As is, this will usually get entered into the subject line. Adding a dedicated place for this (and possibly a note to stop by the Operator shack) will help to streamline the process of attaching FIRs to IMS entries.

OODs have also requested the ability to have a new Incident be created upon submitting a (Field) Incident Report for which it is known a corresponding Incident does not already exist. (OTDB 2023 #234; from OOD AAR).
