Fix a real regression: dynamic-mode windows lost their shadow via toggle_floating

The tiled-shadow-tint fix earlier today gated the shadow on Window::floating
alone. arrange_workspace only reads floating under the "tiling" layout, so
every window on this project's own default "dynamic" layout starts, and
stays, floating: false - the gate misread that as "tiled, no shadow"
regardless of which layout was actually running, so shadows silently
vanished under dynamic mode entirely, recoverable only by pressing Super+S
(toggle_floating), which then looked like that key toggles a tint rather
than floating. Fixed by checking the workspace's own layout name first:
a window is only "currently tiled" when its workspace runs "tiling" AND
it hasn't opted out via floating. DecorationSignature's floating field is
now currently_tiled, since a layout switch changes this for every window
on a workspace without touching any of their own floating fields.

Also disabled general.shadows in the user's own config per direct
request - never asked for, on by default, and a real problem for
color-accuracy work regardless of how correctly it renders otherwise.

Also fixed both context menus (titlebar and desktop) silently truncating
labels past a fixed 170px width with no indication - widened dynamically
to each menu's own real widest label via a new measure_text_width helper.
