app: tool page converge button for enabled-but-not-installed drift

The path-tool lifecycle offered only Enable/Disable (keyed on enabled), so an enabled-but-not-on-PATH tool showed just "Disable" with no way to converge it. Add an Install/Uninstall (apply) action whenever desired (enabled) and actual (installed) disagree.
