fix(gestures): a swipe ends the login settling phase

Restored windows pan the camera on their first focus only once the
session has seen deliberate input, so apps settling in at login do not
drag the view around. Only button and key presses counted, so a login
navigated purely by three-finger swipes left each restored window's
first focus wherever it sat, often half off screen, while a second focus
of the same window panned.

The start of a touchpad swipe or pinch now counts as deliberate input
too. A hold does not, since one begins whenever fingers rest on the pad,
and pointer motion still does not.

+Restored windows map unfocused, and their FIRST focus pans the camera only
+once the session has seen deliberate input (`WindowManager::startup_input_seen`,
+gated in `Seat::focus`), so apps settling in at login do not drag the view
+around. Deliberate means a button press, a key press, or the start of a
+touchpad swipe or pinch (`handle_swipe_begin`/`handle_pinch_begin`); pointer
+motion and a hold do not count. Swipes were added on 2026-09-26: a login
