feat(earth): toolbar zoom improvements and toggle-cables

- Remove zoom slider, implement click/hold zoom behavior (+/- buttons) - Add 10% step on click, 1% continuous on hold - Add box-sizing/padding normalization to toolbar buttons - Add toggle-cables functionality with visibility state - Fix breathing effect: faster pulse (0.008), wider opacity range (0.2-1.0) - Fix slider null error in updateZoomDisplay - Set satellite default to hidden
