Sayali: 🔥 change promotion-eligibility endpoint from GET to POST to resolve req.body.requestor undefined issue in production

[sayali-2308]

Description

Fixes production bug where Promotion Eligibility table showed "Failed to load Reviewers" error.
The GET /api/promotion-eligibility endpoint was checking req.body.requestor for permissions, but GET requests don't reliably carry a body in production environments, causing req.body.requestor to be undefined and the permission check to fail with 403.
Fix: Changed the endpoint from GET to POST so req.body.requestor is always populated by the auth middleware.

Related PRS (if any):

Frontend PR required: update promotionActions.js to call axios.post instead of axios.get for PROMOTION_ELIGIBILITY endpoint.
…

Main changes explained:

Updated src/routes/promotionEligibilityRouter.js — changed /promotion-eligibility route from .get() to .post()
…

How to test:

1. Check out branch Sayali_Fix_PromotionEligibility_Requestor
2. Run npm install, npm run build, npm run start
3. Ensure frontend is running on localhost:5173
4. Log in as admin
5. Navigate to localhost:5173/pr-dashboard/promotion-eligibility
6. Verify table loads with reviewer data (no "Failed to load Reviewers" error)
7. Verify dark mode works

Note:

This is a backend-only fix. A corresponding frontend PR is needed to change axios.get to axios.post in promotionActions.js.
