Use app-server skill metadata directly in the TUI (#34368)

## Why

The TUI already receives skill metadata from the app-server protocol, but converted it into the core-skills model before using it.

## What changed

- Use `codex_app_server_protocol::SkillMetadata` throughout skill toggles, mentions, and input submission.
- Remove the protocol-to-core conversion and the TUI's `codex-core-skills` dependency.
