test(document): cover all five DocumentStatusChip status branches

Adds DocumentStatusChip.svelte.test.ts asserting one branch per
DocumentStatus value (PLACEHOLDER, UPLOADED, TRANSCRIBED, REVIEWED,
ARCHIVED) plus the title/aria-label exposure. Each test queries the
element via getByTitle so the component's accessibility surface is
verified at the same time as its branch logic.

Refs #496.
