v1.9.2 — Fix Select All indeterminate state

Fixed

• Select All / section checkbox stuck in indeterminate (—) state — clicking the label area (div, not the checkbox itself) programmatically flips checked but the browser does not clear indeterminate in that path; doToggle() and selectAllToggle() now explicitly reset indeterminate = false so the checkbox always reflects the true all-checked or all-unchecked state after a toggle
• Faded — when nothing is selected — same root cause; indeterminate could remain true even when zero sub-entries were selected, showing a washed-out dash instead of a clean empty checkbox
