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

Migrate cpu, cpu_usage, cpu_frequency and memory to the generic
updateLabelAndTooltip/ForState helper so label and tooltip rendering go
through the dedup-aware setters and shared tooltip-format resolution.

Add store-accepting overloads of the helper to ALabel for modules that
build a dynamic fmt argument store (per-core cpu stats). cpu keeps its
tooltip-format-<state> selection via the state overload; the others keep
their existing tooltip-format-only behavior.
