feat: Souq native integration + auth simplification + CE-wide enhancements

Souq Marketplace:
- Native souq pages: browse+filters, create listing, detail+seller profile, orders+chat
- New API: reviews (POST), sellers/[id], upload (multipart), polar-checkout webhook
- Listings API enhanced: minPrice, maxPrice, sortBy, deliveryDays filters
- Seller workflow: start order, mark delivered, upload files, confirm delivery
- Wallet: 5 Polar.sh FLH tiers, production checkout, mock fallback, success banner
- Fix: order redirect /souq/history → /souq/orders

Auth System:
- Unified auth page, removed OAuth provider routing (2 files deleted)
- Deleted oauth.ts (319 lines) — simplified auth chain
- Streamlined login/register API routes

Prisma Schema (+179 lines):
- New models: Listing, Purchase, Review, Group/GroupMember
- Gamification: DailyStreak, XpTransaction, Achievement, UserLevel
- Learning: LearnCourse/Module/Enrollment/Certificate
- Notifications, Referrals, Dhikr, PremiumBenefits

Deleted legacy code:
- src/app/api/marketplace/* (3 files) — replaced by /api/souq/*
- src/app/api/files/[listingId]/route.ts — replaced by /api/souq/upload
- src/app/api/seller/[sellerId]/route.ts — replaced by /api/souq/sellers/[id]

Infrastructure:
- Dockerfile: standalone output, Prisma runtime migration
- docker-compose.yml: Polar env vars, healthcheck fix
- docker-compose.staging.yml: staging on port 4014
- .gitea/workflows/ci.yml: CI pipeline
