Loan Policy Editor - Add new form fields for Request Management subsections

This story represents the work needed to extend the loan policy form to include the new request-related form fields.

Current mockup: Attached and https://drive.google.com/file/d/1ldfyzoWiPJbOAs0ATwF7TrOjbsX_h5Xk/view?usp=sharing

Scenario:
For Loan Policy where:
Loanable=Y

The following new settings can be considered in-scope:

• 'Recalls' section:
  • Minimum guaranteed loan period
    • [Integer text box + Interval select-list: Minutes|Hours|Days|Weeks|Months]
  • Recall return interval
    • [Integer text box + Interval select-list: Minutes|Hours|Days|Weeks|Months]
    • Note: 0 is valid integer value
• 'Holds' section:
  • Alternate loan period at checkout for items with active, pending hold request
    • [Integer text box + Interval select-list: Minutes|Hours|Days|Weeks|Months]
  • Allow renewal of items with active, pending hold request
    • [Checkbox; default=unselected]
  • Alternate loan period at renewal for items with active, pending hold request
    • [Integer text box + Interval select-list: Minutes|Hours|Days|Weeks|Months]
• 'Pages' section:
  • Alternate loan period at checkout for items with active, pending page request
    • [Integer text box + Interval select-list: Minutes|Hours|Days|Weeks|Months]
  • Allow renewal of items with active, pending page request
    • [Checkbox; default=unselected]
  • Alternate loan period at renewal for items with active, pending page request
    • [Integer text box + Interval select-list: Minutes|Hours|Days|Weeks|Months]

Note: Attachment and linked mock-up show 'Pages' section in gray, to note the ability to collapse the accordion to hide sub-sections while editing. When expanded, this sub-section should include the fields listed above.

Tasks include:

• Adding new UI fields as noted above
• Ensure that back-end schema is updated to include these new fields
• Ensure that values are being appropriately stored

(Question for development consideration):

• How easily will the schema accommodate form fields with duplicate labels and data types, although they occur in different Request Type sub-sections? See field settings for Holds and Recalls above.
