Add a toggle button ("Filters ▼ / ▲") above the quote list on the
browse page. Filter controls are hidden by default and expand when
clicked. Each filter (Author, Tag, Date range) is on its own labelled
row with consistent styling. Existing API query logic is unchanged.

Check GET /api/status on mount; if submissions_locked is true, hide the
form and show a .submissions-closed-banner instead. Fail-open: on error,
treat as unlocked and display the form normally.
