fix: window came up short, clipping the bottom of the interface

initApplication read getInsets() straight after setVisible() and sized
the frame from the answer -- but at that point the window manager has
not decorated the window yet, so AWT returns a guess. Under KWin the
guess is top=25 where the real title bar is top=56, and the guess is
scaled too, so at uiScale 2 it is top=12. The frame is sized from it and
comes up short by the difference: 26px at 1x, 42px at 2x.

The canvas is added to the frame's default BorderLayout, so it is
stretched to that short content area rather than clipped by it -- the
bottom rows of the interface (chat entry, chat tabs, orb row) are never
drawn, and there is nothing to scroll to. Pre-existing; doubling the
scale doubled the loss and made it obvious.

Frame sizing now targets a CONTENT area of exactly canvasWidth x
canvasHeight: awaited briefly before the first paint (the real insets
land ~15ms later), then re-applied by mainredrawwrapper's existing
periodic canvas pass. Each distinct target is requested once, so a
window manager that refuses a size is not fought with forever.

Measured under KWin at uiScale 2: content area 927 -> 1006 device px.
