Show / hide configuration associations (PP-4022)

[tdilauro]

Description

Add an expandable disclosure panel to each row on the integration/configuration list pages, showing the libraries / roles associated with that service. Users can expand/collapse individual rows or use Expand all / Collapse all controls. Alt+Click on any toggle expands or collapses all rows at once.

This is implemented as a set of overridable template methods on GenericEditableConfigList:

• getAssociatedEntries — returns entries to display (or undefined to suppress the toggle entirely)
• formatAssociatedCount — controls the count label (e.g. "3 libraries", "2 roles", "1 registered library")
• getAllLibraries — resolves short names to display names and edit links

Each component overrides as needed:

• Collections / base class — shows associated libraries
• DiscoveryServices — shows successfully registered libraries with their registration stage
• IndividualAdmins — shows admin roles; sitewide roles (manager-all, librarian-all) are pinned to the top; system admins show a synthetic "sysadmin" entry
• Libraries — suppresses the panel (libraries are not associated with other libraries)

Also includes a few minor fixes picked up along the way:

• UNSAFE_componentWillMount update to componentDidMount,
• (window as any).FormData updated to FormData,
• .catch() added to save() to suppress unhandled-rejection warnings, and
• CollectionData now explicitly declares marked_for_deletion.

Motivation and Context

Admins currently have no way to see which libraries are associated with a service without opening each service's edit form individually.
