Apply #ft8-messages container style (border, rounded corners, monospace
font, max-height with scroll) to #ft4-messages, #ft2-messages, and
#wspr-messages which were missing it.
Add #ft4-decode-toggle-btn and #ft2-decode-toggle-btn to the narrow-
screen white-space:nowrap media query rule alongside FT8/WSPR.
Cap DOM rows rendered per history view to 200 (FT8_MAX_DOM_ROWS,
FT4_MAX_DOM_ROWS, FT2_MAX_DOM_ROWS). Full history is retained in
memory; only the DOM representation is bounded. This prevents tab
switching from becoming sluggish after a long decode session where
thousands of rows accumulate in the DOM.
