Plugins declare their own RBAC permissions instead of core accumulating
them: 36 permissions moved out of the core catalog into the 9 owning
plugins (core keeps the 19 its own blueprints enforce). The catalog is
resolved dynamically (core + enabled plugins) and feeds the roles grid,
the token scope picker and ceiling, and flask seed permissions;
installing or enabling a plugin seeds its permissions automatically. A
disabled plugin drops out of the assignable catalog while existing role
links keep working. New plugins - bundled or external - now bring their
permissions with zero core edits.
781 tests pass; live-verified with a machines.edit-scoped token.
