🐛 Bug Fix

Changes

PR #32661 added /coordination_redis/settings and /coordination_redis/settings/test endpoints but did not add them to backend/routes/allowlist.py. The test_gateway_plus_backend_covers_full_app test enforces that every registered route appears in either the gateway or backend allowlist, causing that test to fail with:

AssertionError: 2 route(s) are not exposed on either component.
    /coordination_redis/settings
    /coordination_redis/settings/test

Adding /coordination_redis/ as a prefix entry to the backend allowlist covers both routes and unblocks the CI check

Greptile Summary

This PR adds /coordination_redis/ as a prefix entry in BACKEND_PATH_PREFIXES inside backend/routes/allowlist.py, fixing a CI failure caused by two new endpoints (/coordination_redis/settings and /coordination_redis/settings/test) introduced in PR #32661 that were not registered in the allowlist.

• The single-line addition correctly covers both routes since both begin with /coordination_redis/, satisfying the test_gateway_plus_backend_covers_full_app coverage invariant.
• The placement is consistent with neighboring settings-style entries (/cache_settings, /router_settings) in the "Models & routing config" section, and the PR includes the passing test output as evidence of the fix.

Confidence Score: 5/5

Safe to merge; the change is a one-line addition to a static allowlist tuple with no runtime logic involved.

The change is a single entry added to a read-only tuple. The affected test passes according to the provided output, the prefix /coordination_redis/ cleanly covers both missing routes, and the placement in the allowlist file is consistent with surrounding entries.

No files require special attention.
