Adjust reps dropdown range in workout session logger (#115)

## Summary

- Updated the workout session logger’s repOptions logic so non-AMRAP rep dropdowns now always start at 0 instead of min_reps.
- Updated the dropdown upper bound to end at max_reps + 3, with a fallback to min_reps + 3 when max_reps is unavailable (and 0 + 3 if neither is finite).
- This now produces the requested behavior (e.g., a 6–8 rep range yields options 0 through 11).
