Add SCEvents Landing Page

[trista-chen-29]

issue #2067

Summary

• Implemented /events page in Clark
• Fetches events from SCEvents backend (GET /events)
• Displays events in a responsive card grid
• Feature-gated behind SCEvents.ENABLED

Features

• Loading / error / empty states
• Event metadata (date, time, location)
• Responsive layout (1/2/3 columns)
• Uses existing Clark styling patterns

Notes

• Event creation and registration flows are intentionally excluded (handled in Create SCEvents Event Creation Flow #2068)
• Verified locally with SCEvents running and real data

Testing

• Tested with SCEvents running locally
• feature flag OFF

When SCEvents.ENABLED = false, navigating to /events redirects to the NotFound page.

• feature flag ON

• loading state

• error state

• empty state

• successful data fetch and render

Sample Data

• Used locally created test events via SCEvents backend
• Example response from GET /events:

really awesome work! really appreciate the screenshots + detailed PR; makes reviewing a lot lot easier

could you add one more screenshot where you go to /events with the feature gate off? just want to confirm that the redirecting logic still works as intended

other than that looks great
