chore: fix all lint errors and format codebase

- Remove unused `or` import in comments resolver
- Remove unused `users` import in recordings resolver
- Add index keys to pagination {#each} loops in videos, models, magazine
- Remove stale svelte-ignore comment in header (a11y warnings no longer fired)
