feat: rewrite contribute tab to match web app (app.eventifyplus.com/contribute)
Complete UI rewrite of contribute_screen.dart:
- 3 tabs (My Events, Submit Event, Reward Shop) replacing old 4-tab
layout (Contribute, Leaderboard, Achievements, Shop)
- Compact stats bar: tier pill + liquid EP + RP + share button
- Horizontal tier roadmap showing Bronze→Diamond progression
- Animated tab glider with elastic curve
- Submit form matching web: Event Name, Category, District, Date+Time,
Description (with EP hint), Location Coordinates (manual lat/lng OR
Google Maps URL extraction), Media Upload (5 images, 2 EP each)
- My Events tab with status badges (Approved/Pending/Rejected)
- Reward Shop "Coming Soon" with ghost teaser cards
- Color palette matching web: #0F45CF primary, #ea580c RP orange
- File reduced from 2681 to 1093 lines (59% smaller)
