The network/wifi indicator duplicated nm-applet, which already sits in the
tray (services.network-manager-applet.enable), so remove it from the bar.
And the power-profile speedometer glyph rendered noticeably smaller than
the neighbouring indicators, so bump its font-size (+3pt generated; 20px
summer-day, 17px summer-night).
Applied to the generated bar (waybar.nix) and both whole-swap themes
(summer-day/night waybar.{jsonc,css}) for parity.
