feat: upgrade VeBetterPassport to V5 with per-round participation tracking

[Agilulfo1820]

Summary

• VeBetterPassport V5: Introduces per-round participation tracking with new storage mappings for distinct app counts (userRoundAppCount), per-app action counts (appRoundActionCount), per-user-per-app action counts (userAppRoundActionCount), and total per-user action counts (userRoundActionCount)
• Storage access refactor: Moves getPassportStorage() from the contract into PassportStorageTypes library, allowing all passport libraries to access storage directly instead of receiving it as a parameter — cleaner signatures and reduced calldata
• New view functions: appRoundActionCount, userRoundAppCount, userRoundActionCount, userRoundActionCountApp, userUniqueAppInteraction, userInteractedApps exposed on the interface
• Removed registerAggregatedActionsForRound: No longer needed with the new tracking approach
• Deprecated V4: Previous version preserved under deprecated/V4/ with all its libraries and interface
• CI: Reorganized and expanded test shards for better parallelism (split VeBetterPassport, Governance, GalaxyMember, and others into finer-grained shards)

Test plan

• New round-tracking.test.ts covers userRoundAppCount, userRoundActionCount, appRoundActionCount, and userRoundActionCountApp (distinct app dedup, multi-app, multi-round, delegation)
• Existing upgrade tests updated for V5 initialization
• Existing VeBetterPassport tests updated for refactored library signatures
• CI shard matrix updated — verify all shards pass
