V76 PETAL DIRECT INPUT + 200X SLIDERS

What changed
- All petal sliders now span 0..200 for rough adjustment.
- Each petal parameter row now also has a direct numeric edit box on the right.
- Typed petal values are UNCLAMPED: there is no built-in min/max limit for direct entry, as long as the text is a valid number.
- The Regenerate button now automatically reads the typed values first.
- Added an Apply typed values button so you can update the current values without regenerating immediately.

Parameters with direct input
- Main outward axis
- Main strike full axis
- Opposite petal length
- End outward offset
- End strike length
- Corner outward gap
