feat: publish visit updated for approved visit registration updates and align seed data

[yoganandaness]

Description

Publish VISIT_UPDATED for approved visit-registration updates, include id in visit payload, and update seed data for visit template activation and approved proposals.

Motivation and Context

Ensure downstream systems receive visit update events (not only create/delete) and improve local test data readiness.

How Has This Been Tested

• Verified updated backend files show no editor/type errors.
• Validated message broker routing and payload changes.
• Confirmed SQL seed updates are syntactically valid.

Fixes

Enables visit sync on approved registration updates via VISIT_UPDATED.

Changes

• Updated RabbitMQ publish logic for visit registration events.
• Added id to visit event JSON payload.
• Added active visit template seed.
• Marked seeded proposals as management-approved.

Depends on

None.

Pull request overview

This PR extends the visit-registration event flow so downstream systems can receive “visit updated” notifications (not only create/delete) when an already-approved visit registration is edited. It also introduces a stable id for visit registrations across backend, frontend, messaging payloads, and seed data to improve local/dev readiness.

Changes:

• Backend: add VISIT_REGISTRATION_UPDATED event and publish VISIT_UPDATED to RabbitMQ when an approved registration is updated; include registration id in the message payload.
• Backend/DB: introduce a UUID primary key id on visits_has_users and propagate it through models/records/GraphQL types.
• Frontend/E2E: query and use visitRegistration.id for in-place updates; allow editing approved registrations and add Cypress coverage; align seed data (active visit template + approved proposals).
