chore(lint): manual cleanup batch 1/3 (groups 1-5)

- group 1 (catalog.service): rename categoryId→categoryIdInput param + local categoryId; init pl24Categories with Awaited type; fix img alt + scroll buttons
- group 2 (useButtonType): add type=button to 12 buttons (demo.tsx, index.tsx)
- group 3 (noSvgWithoutTitle): add role+aria-label to 13 decorative svgs
- group 4 (noAssignInExpressions): convert 13 while((m=regex.exec())) → for...of matchAll (pl24-ford-legacy + emex.service)
- group 5 (useExhaustiveDependencies): correct deps in __root user identification, subscription onboarding, model-list-columns; biome-ignore for legitimate single-trigger effects
