Subject: [PATCH] Use fixed hash width for `ty_server` diagnostics (#19766)

Summary
--

Fixes a snapshot test failure I saw in #19653 locally and in Windows CI
by
padding the hex ID to 16 digits to match the regex in
`filter_result_id`.

Test Plan
--

I applied this to the branch from #19653 locally and saw that the tests
now
pass. I couldn't reproduce this failure directly on `main` or this
branch,
though.
