🐛 fix: fix: remove duplicate pacman in command args and normalize CSS across DEs

Fix duplicate pacman invocation in home_page.py and mesa_page.py.
BaseManager._run_pacman_command() already prepends "pacman" to the
command, but four call sites also included "pacman" in the args list,
resulting in "pkexec pacman pacman -S ..." which would fail.

Remove the redundant "pacman" from args in:
- home_page.py: recommended packages install (batch and single)
- mesa_page.py: GPU package install and remove

Also normalize CSS opacities and card backgrounds for consistent
appearance across KDE Plasma and GNOME. The semi-transparent card
backgrounds (alpha 0.60–0.85) allowed the desktop color to bleed
through on Plasma, producing overly saturated tints compared to GNOME.

CSS changes:
- Card base background now uses opaque @card_bg_color
- Kernel group and purpose card gradients end with solid @card_bg_color
- Reduced accent color tint alphas in gradients and borders (~30-40%)
- Lowered box-shadow intensities for softer appearance
- Badge pill backgrounds reduced from 0.18 to 0.12
