The Modal focus-trap effect depended on [open, onClose] and called
panelRef.focus() on every run. Callers that pass a fresh onClose each render
(the common case, e.g. artists-client's closeAdd) re-ran the effect on every
parent re-render — so typing one char into the add-artist search (setQuery →
re-render → new onClose) yanked focus off the <input> back onto the panel,
making the field untypable.
Hold the latest onClose in a ref and depend on [open] alone, so focus-on-open
runs once per open. Fixes every Modal caller, not just add-artist.
Verified live via Playwright: typing "radiohead" one key at a time keeps the
value and document.activeElement on the search input.
