refactor(sway): stash thunderbird in scratchpad instead of hidden ws

waybar's sway/workspaces has no ignore-list (that option is hyprland-only),
so the _tb workspace always leaked into the bar and into super+tab cycling.
Using sway's native scratchpad solves both: the __i3_scratch workspace is
filtered automatically. We run 'floating disable' right after 'scratchpad
show' so the window lands tiled on the current workspace, preserving the
intended UX.
