NetworkGuardButton class
A tap target that guards against duplicate taps and offline submissions.
Wraps onPressed with deduplication (rapid double-taps only run the action once) and disables itself while offline or while a previous tap's action is still running. Fully custom UI via builder; if omitted, a minimal default (child + reduced opacity while disabled) is used.
