fix(types): systemic cleanup of high-impact svelte-check errors

- Resolved Svelte 5 $bindable() prop errors in Analytics and Person Table components.
- Fixed implicit any and type mismatches in QR code and utility functions.
- Corrected OrderBy type mismatch pattern in systemic loaders.
- Improved type safety for BlobPart and ArrayBuffer handling.
- Down to 700 errors from ~731.
