## Problem

Before: the Subprocessor List page
(`/legal/customer-resources/subprocessor-list`) links to the "Updated
October 8, 2026" PDF, added in #51445.

## Solution

After: the page links to the "Updated June 1, 2026" PDF again, until a
page listing all historical lists is built.

How: reverts #51445. Removes `October-8-2026.pdf` from
`apps/www/public/legal/subprocessor-list/` and restores the
`CURRENT_PDF` constant in
`apps/www/pages/legal/customer-resources/subprocessor-list.tsx` to
`June-1-2026.pdf` / `June 1, 2026`. `June-1-2026.pdf` was never removed,
so it is still in place. This is reverted pending a different page
structure.

## Review instructions

1. Open the preview of `/legal/customer-resources/subprocessor-list`.
2. Confirm the button reads "Subprocessor List - Updated June 1, 2026"
and downloads the June 1, 2026 PDF.
