style(themes): brand the launcher mark and rework waybar icon sizing

- Pin `font-family: Nomarchy` on #custom-nomarchy (boreal, executive-slate)
  so the branded mark at U+F000 wins over the Nerd Font's glass glyph at
  the same codepoint (summer bars already pinned it).
- Enlarge the icons on icon+text modules via a Pango span, with a gap so
  the glyph no longer crowds the value. The volume module gets a wider
  gap: its level glyph is unusually wide and overlapped the % otherwise.
- Bump icon-only status modules (caffeine, speedometer, …) to match, so
  they don't read smaller than their neighbours. The generated bar sizes
  everything relative to fonts.size (+2/+3pt) so it scales per theme.
