fix: resolve CI and workspace lint errors (admin + storefront)

- Allow require() in next.config.js (eslint-disable) for both apps
- Replace all catch (e: any) with catch (e: unknown) and proper error handling
- Remove no-explicit-any: add types (PreviewProduct, ProductImage, Id<addresses>,
  ProductDetailReview, error payloads) across admin and storefront
- Admin: use next/image in ImageUploadSection and ProductImageCarousel; remove
  unused layout fonts and sidebar imports; fix products page useMemo deps
- Storefront: use Link for /sign-in in header actions; fix useAddressMutations
  and product detail types; remove unused imports/vars and fix useMemo deps
