Bug: No NCA run when DOSE>1 is selected

[Gero1999]

To reproduce

When in Choose the NCA Profile any DOSE >1 is selected, Run NCA does not progress providing the next message:

INFO [2026-01-22 12:01:52] Calculating NCA results...
ERROR [2026-01-22 12:01:53] Error calculating NCA results:
ℹ In index: 1.
Caused by error in `assert_time()`:
! Please report a bug.
: Error with interval start=47.976, end=72.089: Assertion on 'time' failed: Must be sorted.

Might be due to any of the recent merges later than #911

Expected behaviour

• NCA should be able to be run over all doses
