Peer feedback: users have to type a country code (e.g. "no") when reporting a sighting. Let them type the country name instead, with suggestions. ## Tasks - [ ] Replace the country code field with a country name field with suggestions (e.g. `<input>` + `<datalist>`) - [ ] Get country names from the browser (`Intl.DisplayNames`), no new dependency - [ ] Convert the chosen name to the country code before sending, so the database still stores codes - [ ] Show a clear error if the text doesn't match a known country - [ ] Update the submit page tests ## Done when - [ ] Typing "Nor" suggests "Norway", and submitting stores "no" - [ ] The field works with keyboard and screen reader, and has a visible label
