#9439 Fix unstable location of generated well target at sea level

NB! This fix will update the location of well target at sea level, and can potentially change the MD from sea level to first user defined well target. This will affect completions defined for the modelled well, as they are defined by MD.

* #9439 Make MD more predictable when toggling sea level target.
* #9439 Avoid updating well path tangents when toggling sea level target
* Disable IO of well target at sea level
