Modules duplicated the same boilerplate to format their label and tooltip
(read tooltip-format, fmt::format, set_tooltip_markup) across ~29 modules.
Add updateLabelAndTooltip(labelFormat, tooltipDefault, args...) and its
state-aware variant updateLabelAndTooltipForState(state, ...) to ALabel: they
build a single fmt arg store, render the label and the resolved tooltip format
(tooltip-format[-state] or default) through the dedup-aware setters, honoring
the tooltip toggle. resolveTooltipFormat() centralizes the format resolution.
Migrate temperature and disk as the first adopters.
