feat(settings): add Skills toggle for Codex CLI and improve config editor UX

Add "Enable Skills" toggle below "Enable WebSocket" in Codex CLI settings,
writing `skills = true` under [features] in config.toml. Also add max-height
to auth.json and config.toml textareas, and fix TOML section key insertion
to avoid stray blank lines between entries.
