Benjamin Babeshkin 8a842ed82b Fix local node position overwrite by low-precision echoes ...

When other nodes relay our position via map reports, they send it at
reduced precision (e.g., 13 bits). _onPositionReceive() was blindly
overwriting our locally-stored high-precision GPS position (32 bits)
with these degraded echoes.

The fix only protects the local node's position — since we have the
GPS internally, any lower-precision update is always an echo from the
mesh, never fresh data. Remote node positions are still updated
normally, as any position they broadcast reflects their current state.

Fixes #910
