refactor(tooltip): migrate modules to ALabel generic tooltip helper

Migrate idle_inhibitor, sway/language, sway/scratchpad,
hyprland/language and hyprland/window to the shared label/tooltip
setters. idle_inhibitor uses updateLabelAndTooltipForState; the others
keep their custom label/tooltip resolution (trim, precomputed tooltip,
rewriteString, per-lang/variant formats) and switch to the dedup-aware
setLabelMarkup/setTooltipMarkup.
