style: format tiff-viewer with Prettier

`components/object/tiff-viewer.tsx` was not Prettier-clean on `main`, so
`pnpm format:check` — a required gate in AGENTS.md — failed for every
branch regardless of its contents.

Whitespace only; no behaviour change. Unrelated to the account and
two-factor work in this branch, and separated into its own commit so it
can be cherry-picked or dropped independently.
