feat: palette commands for profile presets and export (F3 follow-up)

Adds "Browse profile presets" and "Export active profile" to the command
palette. Export calls the existing exportProfileToFile directly; presets render
the existing PresetsModal from App via a boolean, avoiding a state lift out of
ProfilesWorkspace.
