* Fix Honeycomb Multiline

Simplify polylines in honeycomb infill generation

* Improve multiline infill support and pattern simplification

Moved multiline infill application after pattern translation and simplification in Fill3DHoneycomb, and added multiline support to FillAdaptive. Updated honeycomb and 3D honeycomb infill to simplify polylines to 5x line width. Extended GUI and config to support multiline for Adaptive Cubic infill pattern and clarified max value comment.

* Increase multiline fill spacing in honeycomb infill

Adjusts the spacing parameter in the multiline_fill function to 1.1 times the original spacing, potentially improving infill distribution or print quality.

* Refine fill_multiline tooltip and pattern support logic

Updated the tooltip for the 'fill_multiline' parameter to improve clarity and punctuation. Refactored the logic in ConfigManipulation.cpp to clarify which infill patterns support multiline infill.

* better management of non supported infill patterns
