SPONSOR-01 - Hero + sponsor of the week (frontend)

[oorjagandhi]

Description

Customise the shared hero component on the top to match Figma. Create sponsor of the week component.
Check in #backend or Joe if there is an endpoint ready to fetch data, if not just hardcode a mock event.

Design

Figma link
Double check with designer before implementing 'sponsor of the week' component - component could be shared / copied from 'upcoming event' card.

Acceptance Criteria

• The shared hero component is customised for the Sponsors page with the correct title ("Sponsors"), subtitle text, background colour, and mascot image per Figma
• A "Sponsor of the Week" section is displayed below the hero per the Figma design
• The call to action button is displayed with correct styling and layout per Figma (links to sponsor website URL)
• Check with Joe/#backend whether a Sponsor of the Week endpoint is available before starting
• If no endpoint is ready, the component is built with hardcoded mock data that reflects the expected CMS schema (name, logo, websiteURL, isSponsorOfTheWeek, description)
• Mock data is clearly commented for later replacement
