SP form: compact layout; v1.9.10

- SPI1/SPI2 side by side in one row
- KIc/KID byte selectors side by side in one row
- KIc/KID key textareas moved directly under the KIc/KID selectors
- Card preset selector moved to the top of the form, full width
- Padding byte joins TAR + Counter in one three-column row
- Pure HTML reflow: no id/handler changes, all behavior preserved
  (invalidation, presets sync, por_ok counter bump)

Version 1.9.9 -> 1.9.10 everywhere; SW cache otaman-v20 -> otaman-v21
