feat(compose): a menu bar on the composer

File, Edit and Format, to the scope the user chose. Save draft (Ctrl+S)
is the only new action: saveDraftNow() was reachable from the autosave
timer, the send path and closeEvent, so there was no way for the user to
ask for a save. It routes through that same function, which is what
emits draftSaved for item 158's indexing, reports through item 160's
status bar and raises the failure banner; a second write path would have
to repeat all three.

The menus show the toolbar's own QAction objects rather than copies, as
item 140 required for the message pane's bar. Two needed hand-building.
The HTML toggle is a QToolButton and cannot go in a menu, so a checkable
twin mirrors it in both directions, since a menu entry that only follows
the button is half a control. The signature entry takes the switch's own
QMenu pointer, because that menu is rebuilt whenever the signatures
change and copied entries would go stale.

Edit's entries drive QPlainTextEdit and follow its own undoAvailable and
copyAvailable, so a greyed entry tells the truth about what pressing it
would do.

theMenuBarReachesEveryComposerAction() is item 132's reachability rule
applied to the composer: it walks the real menu bar and collects the
composer's actions with findChildren, so an action added to the toolbar
and forgotten in the menus fails without the test being touched. It
skips actions owning a submenu, since Qt emits no triggered for those.

The composer's actions stay out of KeyMap, per item 148: they are
parented to this window, so they are WindowShortcuts dispatched to the
active composer and the main window's namespace is untouched.

lrelease reports 496 finished, 0 unfinished.

Closes item 161.
