feat(mail-overview): the drawer

Builds the panel body on the house idiom the other two components already
use: a fullscreen transparent PanelWindow holding a dim backdrop, with the
real content as a Rectangle anchored inside it. The idiom is worth the
seemingly oversized window because it hands us two behaviours for free.
Click-outside-to-close is just a MouseArea filling the backdrop, and the
drawer only needs its own MouseArea to swallow clicks so they do not fall
through. Escape works because the window actually covers the screen and can
take exclusive keyboard focus.

exclusionMode is Normal here, unlike the Ignore the other two components set.
Waybar claims an exclusive zone at the top of this screen, and the mail icon
lives in it, so respecting that zone positions the drawer immediately below
the bar without this file hardcoding, or even knowing, the bar's height. It
also means the backdrop begins below waybar, so the bar itself does not dim
while its own drawer is open, which reads correctly: the icon you clicked
stays lit.

Focus sits on an inner Item with focus: true, not on the window. Setting
WlrLayershell.keyboardFocus is necessary but not sufficient, because key
events in QML are delivered to a focused item and never to a window, so
Keys.onEscapePressed on the PanelWindow would never fire. This cost time in
the vm-manager panel and the same shape is used here deliberately.

Thread rows are deliberately read-only, with no click handler. qtmaildir
takes no arguments, so there is no way to ask it to open a particular thread
and a clickable row would promise navigation it cannot deliver. The rows are
a preview; the button opens the client at its own idea of where to start.

show() refreshes before opening rather than relying on a timer. The panel is
opened rarely and the shell is autostarted for the whole session, so the
counts are almost always stale by the time anyone looks at them, and a
refresh on open is both cheaper and fresher than polling.

Also removes the temporary console probe from shell.qml, which existed only
to verify the account model parsed and counted correctly. The drawer now
displays the same data, so the probe has no job left. Dropping it also drops
the QtQuick import, which nothing else in that file needed.

Button.qml is an unmodified copy of vm-manager's.
