Protocol Changes

• Sets chunk_validator_only_kickout_threshold to 70. Uses this kickout threshold as a cutoff threshold for contribution of endorsement ratio in rewards calculation: if endorsement ratio is above 70%, the contribution of endorsement ratio in average uptime calculation is 100%, otherwise it is 0%. Endorsements received are now included in BlockHeader to improve kickout and reward calculation for chunk validators.
• Changes the way receipts are stored in the state for the purpose of correct gas and size calculations in congestion control
• Storage compute costs for function calls are lowered (read_base, has_key, read_value, touching_trie_node) and a new large_read_overhead is introduced for reads of values over 4k. See https://github.com/near/nearcore/issues/11925 and https://github.com/near/nearcore/pull/12044

Non-protocol Changes

• RPC: started using non 200 HTTP codes for some errors, see the details here
• Added documentation and a reference script to recover the data lost in archival nodes at the beginning of 2024.
• Archival nodes only: Stop saving partial chunks to PartialChunks column in the Cold DB. Instead, archival nodes will reconstruct partial chunks from the Chunks column.
