Fix Fastly tiered cache diagram alignment in popup

The ASCII diagram showing X-Cache header breakdown had misaligned arrows.
The vertical lines were offset by 8 characters, pointing to wrong positions
in the header value.

Before:
X-Cache: MISS, HIT, MISS
 │     │    │

After:
X-Cache: MISS, HIT, MISS
         │     │    │

Also syncs CHANGELOG.md with git history - v0.0.9 content was incorrectly
still under [Unreleased] despite the tag already existing.
