On a light background (Catppuccin Latte in Ghostty on macOS) the panes
kept palette color 0, a dark grey slab with white text. The probe now also
asks for the text color (OSC 10). Light backgrounds are used as well, with
text, borders and titles in the terminal's text color, input fields and
buttons in a light shade of it, and the active tab drawn in it.

The check only looked at COLORTERM, but tcell also draws 24-bit color for
terminals whose description has it (xterm-ghostty, xterm-kitty), so in
Ghostty on macOS without COLORTERM the background was never used. Use
tcell's rules, and always log which background is used and why.

The panes used palette color 0, which color themes such as Catppuccin set
to a grey lighter than their background: everything looked washed out and
grey text almost disappeared (seen in Ghostty on macOS). The startup probe
now also asks for the background color (OSC 11), and with 24-bit color and
a dark background that color is used. The probe always runs at startup, so
a later switch to real images in the Config view never has to ask the
terminal while the screen owns it.

On a terminal zoomed far out a poster is tens of thousands of cells, and
redrawing it on every step of a held arrow key was more output than the
terminal could draw (about 100 KB per step at 600x180), so the list
lagged. A selection that changes again within 120 ms keeps the poster's
place empty and shows the poster once it rests.

Terminal.app draws block elements from the font, with the halves off the
cell's middle, so quadrant posters came out as rows of shifted dots. The
new cover style "cells" uses one background color per cell and no glyph;
auto picks it when TERM_PROGRAM is Apple_Terminal.
