fix(api): disable mongoose autoIndex in check-alerts worker

[Vansh98789]

Summary

The check-alerts worker only reads from MongoDB and never needs to ensure indexes exist-the API service owns that responsibility.

Previously, Mongoose's autoIndex triggered background createIndexes calls that raced with the worker's short-lived connection closing (which sends endSessions). This surfaced as MongoExpiredSessionError on mongodb.createIndexes spans.

This PR:

• Disables auto-indexing for the worker connection via connectDB({ autoIndex: false }).
• Removes the now-redundant mongoose.set('autoIndex', false) from init().

Files Changed

• packages/api/src/models/index.ts

Hi @pulpdrew
Deep review is failing due to pull_request_target fork-checkout restrictions since this is from a fork -might need maintainer approval or a workflow tweak.
