Realtime KDS via Server-Sent Events
Deploy Ladill POS / deploy (push) Successful in 1m22s

Browse Source 
Replace the kitchen display's 4s polling with a pushed feed. GET /kitchen/stream
holds an SSE connection and emits the board the moment it changes (~1s tick,
heartbeat between changes), so fired/bumped/guest orders land on screen near
instantly. Bounded to ~25s per connection so PHP-FPM workers recycle — the
browser's EventSource reconnects automatically; if EventSource is unavailable it
falls back to polling /kitchen/feed. Sends X-Accel-Buffering: no so nginx streams
it, and releases the session early (DB sessions don't lock, but be safe).

feed()/stream() now share buildTickets(); behaviour of the JSON feed (initial
load + fallback) is unchanged. Suite green (12).
