feat(plugin-inventory): add setEnabled Remote that toggles and persists a plugin

pluginInventory/setEnabled calls ctx.loader.update({disabled}) for a live
effect and writes an explicit disabled override into the profile's user
patch layer so the choice survives a restart. The patch row id is the bare
entry options.id, not the group-prefixed tree id.
