fix: locale/unicode compatibility in quickinfo, bump PRbL submodule

- Pin LC_ALL=C on free/uptime/sensors calls parsed by grep/awk on
  English words and fixed column positions; these broke under
  non-English locales. Uptime's token-position parsing is still
  format-fragile across procps versions/distros; noted as a follow-up
  for a /proc/uptime-based rewrite.
- Replace hardcoded '°C' with a deg_symbol variable that collapses to
  plain "C" when PRbL/functions reports unicode_supported=false, so
  temperature readouts stay pure ASCII on terminals/locales that can't
  render the degree sign.
- Bump PRbL submodule for the ANSI-code and box-border fallback fixes.
