Pick window transparency from Appearance > Window Transparency, and a Glassy bar background (#14991)

* Pick window transparency from Appearance > Window Transparency

Transparent, the default, keeps today's windows. Opaque turns the windows
Omarchy makes transparent solid. Glassy is the frosted glass Starship
(#14726): its blur behind every see-through window and shell surface, and a
see-through, blurred background in the theme's terminal files, since foot
turns compositor blur down and a Hyprland opacity rule fades text.

* Leave window transparency to Appearance when animations are off

Turning animations off no longer makes windows opaque. VM installs start
with opaque windows instead, and a migration keeps them opaque for anyone
who already has animations off.

* Add a Glassy bar background, under Menu Bar > Bar Background

Menu Bar > Bar Background picks Opaque Bar, Glassy Bar or Clear Bar, and
Indicators becomes Bar Indicators to match. Glassy keeps the theme
background faintly and Hyprland blurs what is behind it, with the same blur
as Glassy windows.

omarchy bar background opaque|glassy|none|cycle sets it and prints it when
given nothing. omarchy bar transparent true|false|toggle stays for
compatibility, as none and opaque. Double-clicking the bar cycles through
the three backgrounds the same way, from clear to glassy to opaque.

 The bar config lives under the `bar:` key of [`~/.config/omarchy/shell.json`](../../../docs/omarchy-shell.md#shelljson). Out of the box the shell uses [`config/omarchy/shell.json`](../../../config/omarchy/shell.json).
