the client starts remembering: zoom, camera, filters, a Combat page

- minimap zoom and the camera's distance and pitch persist across sessions
- the trainer's point-filter is a saved variable now and survives a relog, resetting per packet like the reference
- the options window gains its Combat page, over rows that can write the UI's own saved globals
- the step-up is a rise, not a jump forward — and the descent cone's cap belongs to the body, on every leg
