Description

• Space updates: description, icon, image, readme, quota and restore requests no longer send the cached name, so they don't undo a rename made elsewhere.
• Admin user quota: the batch "Edit quota" no longer sends the user's display name as space name, which failed with 400 for names like "Dr. John Smith".

Related Issue

• Fixes Space and quota updates send the cached name: they undo renames made elsewhere and fail for user names with a dot #3674

How Has This Been Tested?

• test environment: unit tests (Vitest); PATCH without name (quota, description, restore) verified against a local OpenCloud backend
• test case 1: QuotaModal sends only { quota } for a space named "Dr. John Smith"
• test case 2: editing the description sends only { description }
