LiveView for creating and editing post groups (collections).

Groups are user-specific collections for organizing posts. Each user can create groups with unique slugs within their own collection (Pinterest-style).

Features

• Group Creation: Create new groups with name, description, slug
• Group Editing: Update existing group details
• Slug Management: Auto-generate or manually set URL-friendly slugs
• Visibility Control: Public or private group settings
• Validation: Ensure slug uniqueness within user's groups

Route

• New group: {prefix}/admin/posts/groups/new
• Edit group: {prefix}/admin/posts/groups/:id/edit

Note: {prefix} is your configured PhoenixKit URL prefix (default: /phoenix_kit).
