fix(admin): pass personId through load fn instead of params prop; widen touch targets in table rows

SvelteKit page components receive only data/form as props; accessing params
directly caused a TypeError and personName always fell back to 'Unknown'.
Also moves py-3 padding from <td> to <a> in OcrModelsTable to give
keyboard/touch users a full-height 44px target (WCAG 2.5.5).
