EVENT-13 Event Gallery Page (frontend)

[oorjagandhi]

Description

Build the gallery page for a past event. When a user clicks a past event card, they are taken to this page which displays the event's images in a gallery layout. Images are sourced from the images array on the Event returned by the CMS API.

Depends on #39 for real data, but can be built with mock image arrays in the meantime.

Design

Figma link

Acceptance Criteria

• The gallery page renders the images array from the event as a grid layout per the Figma design
• Layout is responsive across mobile, tablet, and desktop
• No event metadata is displayed — images only
• The page is reachable by clicking a past event card
• The correct event's images are displayed based on the event slug or ID in the URL
• If an event has no images, an empty state is shown with a message

Additional Notes

• Gallery is just an array of uploaded images on the Event — no separate endpoint needed beyond what EVENT-11 - Connect to CMS Backend #39 exposes
• Confirm the URL structure with backend (slug vs ID) so routing is consistent
