perf: Add missing indexes on foreign keys referencing documents (#12473)

* perf: Add missing indexes on foreign keys referencing documents

Cascade deletes on the documents table were forced into sequential scans
on file_operations, share_subscriptions, and access_requests because
their documentId columns lacked a usable single-column index.

Also fixes lint-staged to skip oxlint when every staged file matches an
.oxlintrc.json ignore pattern, since oxlint exits 1 in that case.

* Handle oxlint no-files exit instead of mirroring ignorePatterns
