Add job failure alerting for analytics cron jobs

[phertyameen]

Description

Wrap each analytics cron job in a try/catch that logs failures with enough context to debug, and emits a analytics_job_failed event so it can be surfaced (e.g. to logs/alerting) if a rollup silently stops running.

Why this matters

A silently-failing nightly job would produce stale dashboard numbers with no obvious signal that anything is wrong.

Files to touch

• backend/src/analytics/jobs

Acceptance Criteria

• Job failures are logged with job name, error, and affected date range
• A failed job does not crash the app or block other scheduled jobs

Notes

This issue is part of the new analytics module effort (tracking, aggregation,
and reporting on player/game activity). Please keep new code inside
backend/src/analytics/ following the same module/controller/service/provider
layout used by existing modules (e.g. progress, streak, quests).

Hello! I'd like to work on this issue.

From my understanding, the goal is to improve the reliability and observability of the analytics cron jobs by ensuring each scheduled job is wrapped in proper error handling.

My implementation will:

• Wrap each analytics cron job in a try/catch block.
• Log failures with sufficient context, including the job name, error details, and the affected date range, to make debugging straightforward.
• Emit an analytics_job_failed event whenever a job fails so it can be surfaced through the project's existing logging or alerting mechanisms.
• Ensure that a failure in one scheduled job does not crash the application or prevent other scheduled jobs from running.

I'll follow the existing backend architecture and keep all new code within backend/src/analytics/, maintaining consistency with the project's module/controller/service/provider structure.

I'd be happy to take on this issue and look forward to contributing. Thank you for your consideration!
