feat(dashboard): redesign Featured Contributors & Discoverers spotlight with centered row layout

[dataCenter430]

Summary

• Replaced the old DashboardTopContributors 3-column grid with a clean horizontal row card layout for both FeaturedContributorsSpotlight and FeaturedDiscoverersSpotlight
• Each card uses a 3-column CSS grid (1fr auto 1fr) so the stats block is always visually centered and vertically aligned across all rows
• Added rank-accent left strip per card (gold/silver/bronze) as a visual differentiator
• Score value rendered in a subtle boxed chip with rank accent color; cred progress bar also uses rank color
• Full-width KPI strip added below each section header showing aggregated metrics
• Removed left border section indicator from both spotlight wrappers for a cleaner look
• Extended dashboardData.ts contributor builders with score, mergedPrs, closedPrs, and earnings fields to supply the new UI
• Wired FeaturedContributorsSpotlight into DashboardPage replacing the old component
• Fixed mobile responsive layout: KPI strip scrolls horizontally instead of overlapping; stats column right-aligns on small screens (xs: 1fr auto auto, sm+: 1fr auto 1fr)
• Removed all unused imports and props; passes lint, TypeScript, and build checks

Test plan

• Featured Contributors renders 3 rows with gold/silver/bronze left strips
• Featured Discoverers renders 3 rows with gold/silver/bronze left strips
• Stats column (score chip + count + cred bar) is vertically aligned across all 3 rows in both sections
• KPI strip shows correct aggregated values
• On mobile: KPI strip scrolls horizontally, stats are right-aligned
• On desktop (sm+): stats are centered between identity and repo pills
• Repo pills visible on md+ screens, hidden on smaller
• Clicking a row navigates to the correct miner detail page
• Loading and empty states render correctly
• npm run lint, tsc --noEmit, and npm run build all pass

Closes: #873

Hi, @anderdc
I'd appreciate your feedback with this.

DRIFT detected — original PR premise tackled redesigning Featured Discoverers with responsive layout, the current state may not align. Flagging for maintainer review.

• The PR expanded from a focused Featured Discoverers redesign (mirroring feat: redesign dashboard featured spotlights #874's Contributors work) to bundling both Contributors and Discoverers into a single PR, doubling the original scope.
• Original title and body targeted only FeaturedDiscoverersSpotlight; current state absorbs the Contributors redesign (feat: redesign dashboard featured spotlights #874) as well, tracking two distinct component rewrites in one PR.

add tool tips to explain anything that isnt self explanatory. make sure all data is correct (some is displaying incorrect, example. 6 touched repos for discoveries is impossible). remove names of repos and show show PFPs. remove sentence from under the title.

Closing — same reasoning as #874: too complex, no clear takeaway from the section. The vertical horizontal-row layout breaks the dashboard's card-grid rhythm, eats roughly 3× the vertical space the current 3-column grid uses, and the two new spotlight files are ~80% duplicates of each other (123 of 662 lines differ). If you want to take another pass, the parts worth keeping are the rank-accent strip, the Eligible/Pending badge, and the section-level KPI strip — applied inside the existing 3-column grid, in a single shared component.
