Remove mobile filter chip bar from repertoire page

The sticky chip bar added noise: users already see their active
filters highlighted in the accordion columns (with rep-entry--selected
styling and the active-count badge on each toggle). Removing chips
shifts focus back to the accordions, consistent with the expectation
that users return to the dropdowns to adjust filters.
