Restores the original intent that T-226's refinement wording lost: the
shift modifier is the explicit opt-in for bypassPermissions, not a
separate confirm flow. Plain Ctrl/Cmd+M keeps cycling the safe trio;
Ctrl/Cmd+Shift+M cycles the full list. The composer menu's bypass row
was permanently disabled, deferring to "the cockpit's confirmed path" —
but that roster is ghost-fed (T-396), so bypass was unreachable from
the primary session's UI entirely. The row now no-ops on a plain click
(menu stays open) and selects on shift-click, with a hint naming the
gesture. Roster badge and /permissions paths unchanged.
lib/test_app.dart is a format-only follow-up to the previous commit.
