Standardize prerelease version tags for mobile apps. Updated client and staff pubspecs to use 0.0.1-m3 instead of their previous Iliana*-M3 suffixed versions: - apps/mobile/apps/client/pubspec.yaml: 0.0.1-IlianaClientM3 -> 0.0.1-m3 - apps/mobile/apps/staff/pubspec.yaml: 0.0.1-IlianaStaffM3 -> 0.0.1-m3 This keeps version naming consistent across the mobile projects.
