feat(mobile): Enable shared/lib imports via symlink for production blockchain integration

- Create symlink mobile/shared -> ../shared for Metro bundler access
- Update all @pezkuwi/lib/* imports to use relative paths (../../shared/lib/*)
- Dashboard Roles card now fetches real tiki data from blockchain
- Staking screen uses production getStakingInfo and getAllScores
- All citizenship, referral, and NFT screens use real blockchain queries
