[Frontend] — `AddMatchForm`: bonus/double-points multiplier + `MatchList` badge

[Olowodarey]

Background

src/component/creator-events/AddMatchForm.tsx (173 lines) collects only
teamA, teamB, matchTime:

src/component/creator-events/MatchList.tsx (107 lines) renders each
match's outcome badge but has no concept of a bonus multiplier:

[id]/matches/page.tsx's handleAddMatch (lines 122-142) and Match
interface (lines 22-30) also have no multiplier field.

Goal

Let creators mark a match as a "bonus" (2x or 3x points) match in
AddMatchForm, persist it through addMatch(...) (Issue 1's new
signature), and display a multiplier badge in MatchList.

Acceptance Criteria

• AddMatchForm has a 3-way multiplier selector defaulting to 1x,
• A newly added match with multiplier 2 or 3 shows a "⚡ Nx Points"
• Matches with multiplier 1 show no extra badge (no visual noise for

hi maintainer

I have experience implementing frontend feature enhancements that improve data visibility and user interaction.
I can add a bonus/double-points multiplier field to AddMatchForm and display the multiplier as a badge in MatchList.
My approach ensures proper form handling, consistent UI presentation, and clear visibility of match bonus information across the application.
