fix(models): chunk commit status queries to avoid SQLite expression depth limit (#39611) (#39638)

Browse Source 
Backport #39611 by @Kshot3000

* Fixes #39606
* Fixes #39329

`GetLatestCommitStatusForRepoCommitIDs` built one `OR` condition per
commit SHA. Rendering a commit list of more than ~1000 commits (for
example a large pull request, via `processGitCommits`) therefore failed
on SQLite with `SQL logic error: Expression tree is too large (maximum
depth 1000)`.

The max-index lookup now queries SHAs in chunks of 500 with `IN`, and
the follow-up status fetch runs in chunks of 100 `(index, sha)` pairs,
so the expression depth stays bounded regardless of the commit count.
Results are unchanged.

Verified with a new regression test that calls the function with 2001
SHAs: it fails with the reported error on `main` and passes with this
change. `go test ./models/git/` passes.
