Create model to store IHP draft V-Drive path

[hschallhorn]

Associated with #14980. We need a way to store the location of a draft IHP written by a POA to be QA'd by VLJ support. This ticket is to create a new table to store this information

• Model is associated with an appeal
• Model is associated with an IHP writing VSO
• Model validates and stores properly formatted v-drive path
• TIMESTAMPS

Open questions

• Should a IHP written by a VSO overwrite one they already wrote for an appeal?

Ryan will provide path string validation rules.

Why 1?

Why 2?

• Add new model/table to schema

Why 3?

• Validation of path upon creation and update via regex (along with tests)

Validations!

Here is the link for Legacy Appeals:
V:\VBMS Paperless IHPs\AML\902
This link is specified by each VSO. i.e., DAV\902, VFW\902, etc.
Here is the link for AMA Appeals:
V:\VBMS Paperless IHPs\AML\AMA IHPs
This link is also specified by each VSO. i.e., DAV\AMA IHPs, VFW\AMA IHPs

Looking at the v drive, if a user were to copy a link to the file, it would paste as

"\\vacoappbva3.dva.va.gov\DMDI$\VBMS Paperless IHPs\AML\902\VetName 12345.pdf"
"\\vacoappbva3.dva.va.gov\DMDI$\VBMS Paperless IHPs\AML\AMA IHPs\VetName 12345.pdf"

for legacy and ama appeals respectively where "AML" is the VSO. There seems to be no standard format for the actual PDF name unfortunately. Note that the quotes are included as well.
