Event Waitlist Management System

[krutthiikaaa]

Closes #665

Description

This PR introduces a Smart Waitlist Management System for events that have reached their maximum registration capacity.

Features Added

• Automatic waitlist enrollment when an event is full.
• Real-time tracking of a student's waitlist position.
• Automatic promotion of waitlisted users when a registered participant cancels.
• Notification system to inform users when they are moved from the waitlist to the confirmed attendee list.
• Updated event registration workflow to handle capacity limits efficiently.

Why This Change?

Currently, students cannot register for an event once the participant limit is reached, which may result in unused slots when registered attendees cancel. This feature ensures that vacant spots are filled automatically, improving event participation and user experience.

Changes Made

• Added waitlist data structure and status management.
• Implemented auto-enrollment logic for available slots.
• Added waitlist position calculation.
• Updated event registration and cancellation APIs.
• Added UI components for waitlist status and position display.
• Integrated notifications for waitlist promotions.

Checklist

• Code follows project guidelines
• Feature tested locally
• Documentation updated (if required)
• No breaking changes introduced

Warning

Review limit reached

@krutthiikaaa, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 49 minutes and 58 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.
