SOLIDPOD: grant permission: restore lost webId suggestions from individual recipient popup

[jesscmoore]

Describe the Bug

In the Grant Permissions UI, when I select individual to share an individual, the dialog should show suggestions from the list of recipients of (all) files in my Pod. However, these suggestions dont appear since oct/nov updates to GrantPermissionUI().

Consider also removing the not much used dataFilesMap parameter.

To Reproduce

Steps to reproduce the behavior:
Eg. in notepod:

1. Create a note.
2. Click the share icon, to share it.
3. In the Grant Permisison UI, select Individual
4. In the individual webId text field, there should be a list of suggestion WebIDs to choose from, built from the current list of recipients of any file in my pod. Currently this suggestion list is missing, and the console shows this error:

$ (flutter: Invalid argument(s): No host specified in URI note-20250924T150253.ttl)

Expected Behaviour

If I have any recipients to any files in my Pod, there should be suggestions below the text field.

Screenshots

Here I've created test note, and as other notes have recipients, I should get suggestions when I share test note:

No suggestions shown, so I have to type it in manually:
