Hurlingtennis Booker Enha

Adds filters, colour coding, shortcuts and grouping to Hurlingham Club booking. Hide full slots and spot availability fast.
What it adds to the booking page:

Sticky filter bar at the top: filter by court type (Indoor / All Weather), time period (AM / PM / Evening), toggle to hide full slots
Colour-coded slot borders: green = available, orange = 1-2 spots left, greyed + striped = full
Period dividers (Morning / Afternoon / Evening) so you stop scanning a wall of identical rows
Slot count showing how many are visible after filtering
Keyboard shortcuts: f (hide full), i (indoor), w (all weather), 1/2/3 (morning/afternoon/evening)
Filters persist between visits
