/skills dialog uses toggle-like indicators with no toggle affordance

Problem

The /skills dialog displays:

• Green checkmarks next to each installed skill
• Lock icons next to plugin-managed skills, with text saying they are "managed via plugins"

This visual language strongly implies a toggleable installation state — checkmarks suggest "installed, can be uninstalled" and locks suggest "can't toggle because managed elsewhere." But there is no toggle interaction available. The dialog is read-only.

Why this matters

The checkmark + lock pattern is a well-established UI convention for settings panels with mixed editable/locked items. Users (and AI agents reading the UI) will expect to be able to toggle the non-locked items. When they can't, it creates confusion about whether the feature is broken or just undiscoverable.

Expected behavior

Either:

1. Make the indicators actionable — clicking a checkmarked skill toggles it off (aligns with #26838)
2. Change the indicators — use bullets, dashes, or a simple list format that doesn't imply toggleability. Keep the lock + "managed via plugins" label as informational text without the contrast against toggleable-looking checkmarks.
