feat(math): add blueprint nodes for math library (#442)

* feat(math): add blueprint nodes for math library

- Add Vector2 blueprint nodes (Make, Break, arithmetic, Length, Normalize, Dot, Cross, Distance, Lerp, Rotate, FromAngle)
- Add Fixed32 blueprint nodes (conversions, arithmetic, math functions, comparison)
- Add FixedVector2 blueprint nodes (Make, Break, arithmetic, vector operations)
- Add Color blueprint nodes (Make, Break, conversions, color manipulation, constants)
- Add documentation with visual examples for all math blueprint nodes
- Update sidebar navigation to include math module

* fix(ci): adjust build order - blueprint before math

math package now depends on blueprint, so blueprint must be built first
