fix(frontend): ShareKnowledgeDialog displays user/group IDs instead of names

[mrveiss]

Problem

ShareKnowledgeDialog shows user and group IDs instead of human-readable names in share recipients list.

Root Cause

Lines 195 and 205 have TODO comments indicating API calls to fetch display names are not implemented:

// Line 195
name: userId, // TODO: Fetch user names from API

// Line 205
name: groupId, // TODO: Fetch group names from API

Expected Behavior

• Users should display as 'John Doe (john@example.com)'
• Groups should display as 'Engineering Team'
• Not raw IDs like 'user-abc123' and 'group-xyz789'

Files

• autobot-frontend/src/components/knowledge/ShareKnowledgeDialog.vue

Solution

Add API calls to fetch user/group metadata by ID
