Feature/enhancements and fixes

[Alann27]

Summary

• Removed the Relay entity and its related references across claim processing functions for simplicity and optimized structure.
• Stopped saving some unnecessary fields (like proof, root_hash, etc) to save processing time.
• Added numRelays, numClaimedComputedUnits, numEstimatedComputedUnits and claimedAmount to MsgCreateClaim
• Improved proof validation status handling with fallback for better event processing
• Replaced generation of reports using fetchPaginatedRecords with processing manually with functions that generate the reports directly in the db
• Updated db functions of delegator rewards
• Improved update of balances to do it in bulk of 10 instead of one by one
• Added the followings db functions:
  • get_rewards_by_date db function
  • get_rewards_by_addresses_and_time_group_by_service
  • get_rewards_by_addresses_and_time_group_by_address_and_date

Issue

• Some fields like proof, root_hash, etc; were being so large that they made the indexer crash, we are not using them and don't find any use for them right now.
• We saw some low queries when updating the balances.
• The function fetchPaginatedRecords were only returning 100 items instead all records available, causing some data like the reports to be wrong.
