[Bug]: `GET /bulk-predict/template` CSV template download is unreachable — `backend/routes/bulkPredict.js` is never mounted

[Rudra-clrscr]

Bug Description

backend/controllers/bulkPredictController.js exports downloadBulkPredictTemplate, which generates a downloadable bulk_predict_template.csv. The only route wired to this controller is GET /bulk-predict/template in backend/routes/bulkPredict.js. That router file is never require'd or app.use()'d in backend/server.js, so the template-download feature has no live endpoint. The working bulk-upload flow users actually hit (POST /bulk-predict) lives in a different, already-mounted file (predictionRoutes.js), which has no equivalent template route — so there is currently no way to reach the template download at all.

Unmounted router: backend/routes/bulkPredict.js (entire file, L1–L29)
Dead controller export: backend/controllers/bulkPredictController.js (downloadBulkPredictTemplate, ~L150)
Confirmed missing from app: backend/server.js — no require('./routes/bulkPredict') anywhere, unlike predictionRoutes, emailIntegrationRoutes, imapRoutes, etc. (L35–L40, L263–L266)
The route that is live: backend/routes/predictionRoutes.js L520 (POST /bulk-predict), L609 (POST /bulk-predict/export) — no GET /bulk-predict/template here

Steps to Reproduce

1. Confirm the router is never referenced in the app entrypoint:

   grep -n "bulkPredict" backend/server.js
   # (no output)

2. Start the backend and request the template endpoint:

   curl -i http://localhost:5000/bulk-predict/template
   curl -i http://localhost:5000/api/bulk-predict/template

3. Compare with the actually-registered bulk endpoints from predictionRoutes.js, which do respond:

   curl -i -X POST http://localhost:5000/bulk-predict -F "file=@test.csv"

Expected Behavior

GET /bulk-predict/template should return a downloadable CSV (Content-Disposition: attachment; filename="bulk_predict_template.csv") with the sample text,label header, so users know the expected format before uploading a bulk file.

Actual Behavior

Both http://localhost:5000/bulk-predict/template and http://localhost:5000/api/bulk-predict/template return 404 Not Found, while POST /bulk-predict works correctly via the separately-mounted predictionRoutes.js.

The issue describes a missing endpoint for downloading a CSV template (GET /bulk-predict/template) in a backend application. The controller responsible for this functionality is correctly implemented but is never linked (via require or app.use()) to the main server configuration. As a result, the route is unreachable, leaving users without access to the template they need for bulk uploads. In contrast, the related bulk-upload endpoint (POST /bulk-predict) is properly implemented and functional within a different, mounted router.
