fix: add missing POST method to Render env-group redeploy requests

[devin-ai-integration]

Context

When a Render secret sync is configured with autoRedeployServices enabled and targets an Environment Group, the redeploy step silently no-ops.

In redeployService(), the EnvironmentGroup case iterates serviceLinks and calls /services/{id}/deploys — but without method: "POST" on the Axios config. Axios defaults to GET, which hits the list deploys endpoint (returns 200 with a deploy history array). The sync treats that 200 as success and marks the sync succeeded, but no deploy is actually triggered.

The Service case already had method: "POST" and worked correctly.

- request.request({ ...req, url: `/services/${link.id}/deploys`, data: {} })
+ request.request({ ...req, method: "POST", url: `/services/${link.id}/deploys`, data: {} })

Steps to verify the change

1. Set up a Render secret sync targeting an Environment Group with autoRedeployServices enabled
2. Change a secret in Infisical and trigger a sync
3. Verify that all services linked to the env group are actually redeployed on Render (check Render dashboard → service → Events)

Greptile Summary

This PR fixes a silent failure in the Render secret sync where redeploying services linked to an Environment Group was a no-op. Without method: "POST", Axios defaulted to GET on the /services/{id}/deploys endpoint, which returns the deploy history with a 200 status — so the sync appeared successful but no redeploy was triggered.

• Adds method: "POST" to the EnvironmentGroup branch of redeployService(), making it consistent with the already-correct Service branch.

Confidence Score: 5/5

Safe to merge — single-line fix that aligns the EnvironmentGroup code path with the already-working Service path.

The change is a one-line addition of method: "POST" that brings the EnvironmentGroup deploy call in line with the Service deploy call. The root cause (Axios defaulting to GET when no method is specified) is well-understood and well-documented, and the fix matches the established pattern in the same function. No side effects, no new code paths, no schema or API contract changes.

No files require special attention.
