The bare `hermes plugins` picker preselected only rows listed in
plugins.enabled. Bundled platforms, backends and model providers are active
without a list entry, so they opened unticked, and the save on exit wrote every
unticked row into plugins.disabled: opening the picker and leaving without a
change disabled every messaging adapter on the next gateway restart.
Rows now open ticked by the load-time rule (_plugin_status), and only rows the
user flipped are written.
Ported onto the plugins_cmd_toggle sibling and the admission-authority save
(the original targeted the pre-split plugins_cmd.py). The nested
canonical-key composite test now ticks its row explicitly: it handed the menu
a checkbox state that contradicted the config and relied on the old
rebuild-everything save. The original helper-level tests are rewritten
against real admission in a follow-up commit.
