refactor: merge growth-service into platform-service

Phase 1 of service consolidation (5→2 services).

Moved modules:
- invitations (12 tests)
- referrals (9 tests)
- promos (7 tests)

Changes:
- Copied 3 modules + webhooks.ts lib from growth-service
- Added stripe dep to platform-service package.json
- Added webhook env vars to config schema
- Registered invitationRoutes, referralRoutes, promoRoutes in server.ts
- Removed growth-service directory

Tests: 83 passing (was 55 + 28 from growth = 83) ✅
Build: clean ✅
