bugfix(saveload): Restore dock approach flags when loading in DockUpdate::xfer()

[bobtista]

Fixes #3116.

DockUpdate::xfer loads each approach reached flag into a temporary
Bool but never copies it back into the vector. Write it back so the
saved flags are restored. The save format is unchanged.

Verified on MD_CHI01 and a skirmish with multiple supply queues:
1000000000 loaded as 0000000000 before the fix and
1000000000 after it. Slot owners were preserved in both cases.
The queues recovered without the fix; this restores the saved state.

Related: #3151 fixes a separate field in the same function.

Confidence Score: 5/5

The PR appears safe to merge because the transferred flags are now restored consistently in both implementations without altering serialization layout.

Summary

Restores serialized dock-approach flags when loading saved games without changing the save format.

• Copies each value transferred through the temporary Bool back into m_approachPositionReached.
• Applies the same correction to the Generals and Zero Hour implementations.
