Moving projects-list.json behind a route avoids freezing the response at startup, but _build_projects_list() still calls list_projects(allow_cache=True). With the default registry cache TTL of 600 seconds, a newly added project can remain absent for up to ten minutes—the exact startup-empty case this is intended to fix. Please consider an uncached read (or explicit refresh) for this low-frequency UI endpoint and add the regression test described in the PR body; the current diff changes only ui_server.py and contains no test update.

@franciscojavierarceo - Updated _build_projects_list to use allow_cache=False so new projects are visible immediately. Also added the regression test (test_projects_list_dynamic_refresh) and updated the existing tests to hit the dynamic endpoint via TestClient instead of reading the static file from disk. |

@AdityaPatil22 This turns every browser refresh into a full database round-trip, completely bypassing the caching layer that Feast deliberately built. The fix should keep allow_cache=True and let the existing TTL handle staleness. Users who need faster UI refresh can already set cache_ttl_seconds: 10 (or whatever suits them) in their config. I think we can :

@ntkathole - I have added a refresh button in the UI which lets the users invalidate the cache on demand. Please let me know if there needs to be any change in the UI for the button.

no need to change this

The dynamic route is needed for the Refresh button workflow to work correctly.
When a user clicks Refresh:
POST /api/v1/registry/refresh → invalidates the registry cache
GET /projects-list.json → needs to return the updated project list
If we keep only the static file (written once at startup), the Refresh button would invalidate the cache but /projects-list.json would still serve stale data, new projects wouldn't appear in the project selector until the server is restarted.

so, now instead of writing static file which is not being used, can the static file write be removed and all subsequent code be moved inside the with block ?

What this PR does / why we need it:
projects-list.json was written as a static file once at server startup and never refreshed. When a user ran feast apply to create a new project while the UI was running, the new project never appeared in the UI's project list.
This PR replaces the static file write with a dynamic FastAPI route (GET /projects-list.json) that queries the registry on each request, so newly created projects appear immediately on page refresh.
Which issue(s) this PR fixes:
Fixes #6650
Checks
Testing Strategy
Misc
Existing test_projects_list_* tests updated to hit the dynamic endpoint via TestClient instead of reading the static file from disk. New test test_projects_list_dynamic_refresh verifies that mutating the registry after get_app is reflected in subsequent requests — the core assertion for #6650.
