fix: pan the viewport when focusing maximized windows, not just floating

Focus-follow panning was gated on TilingMode::Floating, so focusing a
maximized window (e.g. Electron apps that start maximized) never pulled
the viewport over even when the window was fully off-screen. Maximized
windows live at real desk-plane coordinates just like floating ones, so
widen the gate to both; fullscreen stays excluded (pinned to an output),
as do popups/overlays.
