Fix ped rotation sync is broken when using setElementFrozen instantly (#4566)

Simplify SetFrozen logic and ensure matrix consistency

The `SetFrozen` method was simplified by removing conditional logic
related to `m_pPlayerPed` and now always uses the cached `m_Matrix`
to update `m_matFrozen`. This leverages the fact that `m_Matrix` is
already updated by `SetCurrentRotation`.

In `SetCurrentRotation`, added logic to always update the Z-axis
rotation of `m_Matrix` when setting `fRotation`. This ensures
`m_matFrozen` gets the correct value in `SetFrozen` and maintains
consistency between the current rotation and the cached matrix.
