[BE-25] Events module — CRUD, capacity, RSVP

[yusuftomilola]

Overview

Tech hubs run events constantly — meetups, workshops, demo days. An events system with RSVP is core community infrastructure (every competitor has it) and later a revenue stream ([BE-26] paid tickets).

Proposed Design

New module backend/src/events/:

• Event entity: title, slug, description, coverImageUrl (Cloudinary — reuse backend/src/cloudinary/), startsAt, endsAt, venue (free text or a workspaceId link), capacity (nullable = unlimited), isPublic (visible to non-members), status (DRAFT, PUBLISHED, CANCELLED), createdById.
• EventRsvp entity: eventId, userId, status (GOING, CANCELLED, WAITLISTED), unique (eventId, userId).

Endpoints

Method	Path	Access
GET	/events · /events/:slug	Public lists PUBLISHED+isPublic; members see all PUBLISHED
POST/PATCH/DELETE	/events...	ADMIN/STAFF (publish, edit, cancel)
POST	/events/:id/rsvp · DELETE .../rsvp	Member
GET	/events/:id/attendees	ADMIN/STAFF

Tasks

• Capacity enforcement: RSVPs beyond capacity become WAITLISTED; a cancellation promotes the oldest waitlisted RSVP (notify them).
• Event-cancelled notifications + email to all GOING attendees.
• Reminder job (jobs module, [BE-03]): notify GOING attendees 24h before startsAt.
• Migration included.

Acceptance Criteria

• Full lifecycle works: draft → publish → members RSVP → capacity waitlists → reminder → event passes.
• Cancelling an event notifies every attendee.
• A member can RSVP once and toggle it; unique constraint enforced.

Dependencies

Blocks [BE-26], [FE-11], [FE-12].
