fix(flomni): make fovx=220 inclusive everywhere, default exp_time example to 0.1

- flomni_fermat_scan.py's fovx bound was lt=220 (exclusive), so 220 itself
  was rejected; change to le=220 to match flomni.py's fovx setter, which
  was already inclusive (only raises for val > 220).
- tomo_params.py's flomni fov_fields spinbox max was still 200.0, an
  independent limit that wasn't updated when fovx's cap was raised
  elsewhere -- bring it to 220.0 for consistency.
- exp_time's real default is now 0.1 instead of 0, so the generated scan
  doc's example (scans.flomni_fermat_scan?) shows a realistic exposure
  time instead of 0.
