Fixes #1894

Fixes resampling of Arrow-backed iMOD5 well timeseries when simulation timesteps precede the first well timestep.

The location values are now assigned as scalars per column, avoiding the invalid one-row-to-many-rows Arrow assignment.

Validation:

  • Added regression test reproducing the 92-versus-1 failure
  • All 11 resampling tests pass
  • Ruff checks and formatting pass
  • Updated changelog
