fix(content): strip U+200E from the Jerup entry's coordinates

lat/lng carried a leading LEFT-TO-RIGHT MARK (e2 80 8e), pasted in from a
system that decorates coordinates for bidi text. It renders invisibly, so
the values looked correct while parseFloat saw a non-numeric prefix.

This is the exact input cleanCoordinate() now rejects server-side; the
scan for further occurrences across pages/ comes back empty, so this was
the only affected entry.
