"""Settings dialog navigation: open, tabs, rows, back, text.

Open is retried (single-shot opens flake ~1/4 live): each attempt
re-Escapes and re-drives the dock menu from scratch. Tab clicks are
idempotent (re-clicking the active tab is a harmless no-op), so goto
always clicks and reports the click result instead of guessing which
tab is active.
