Add Fixture

Fixtures are shared across the team. You'll need to run this once in your Supabase SQL editor if you haven't already: create table if not exists fixtures (id uuid primary key default gen_random_uuid(), created_at timestamptz default now(), fixture_date date not null, opponent text not null, venue text not null); alter table fixtures enable row level security; create policy "Allow all" on fixtures for all using (true) with check (true);
