Hotfix for missing variable in no sail boat variant

• Fixed large mast roll in some situations when entering/exiting the boat
• Fixed paddle position and pivot point discrepency
• Sail progress now continues from its partially opened state instead of reseting to closed before opening.
• Minor refactors

This is actually quite a big feature rich update, I wont go into to much technical detail.

• Improved wave motion: Bobbing is now influenced by world position for more natural, consistent waves. This is quite a subtle change but effectively waves now move through world space and boats react to that rather then random wave motions per boat.

• Smoother movement response: Updated velocity estimation to reduce jitter and improve consistency across varying FPS/frame times.

• New paddling animation: Paddles now animate procedurally from your actual movement and turning, including water catch/drag effects. This was a headache that I wanted to do for a while. Previously paddles just hooked into vanilla paddle movement which meant limited control. With this change I now have full control and paddles react to how the boat is actually moving not just user inputs.

• Better sail behavior: Sail ripples now fade out properly when the sail is retracted.

• Sharper damage feedback: Hit reactions trigger more instantly and decay more cleanly.

• Tweaked boat colours to be more in line with vanilla wood colours

I do intend to rework the textures and fix some model UVs to better fit the vanilla style as this is scaled from a 32x32 unreleased pack.

Added no sail variant

• Rename a boat "no_sail"
