fix(desktop): tighter bar icon pad + case-insensitive rofi match

- Double-space pad on volume (esp. high), battery, keyboard layout glyphs
- rofi: matching=normal,fuzzy; case-smart off (ste finds Steam)
- Queue: unfree+calendar PASS; retest spacing + rofi search

V0: nix flake check --no-build green. V3: bar/rofi on session.
