What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Testing

• Add more than 50 evm accounts with the THOR voting power free fees feature flag, all the snapshot requests should success and not be a 429
• FOX voting power should be displayed as usually in the FOX Benefits page
• There should be only a few requests instead of 50-100

Works!

Though I did notice an issue when adding many accounts, ticket raised here
#8077

Also noticed that voting power for added accounts is not re-fetched until the page is reloaded, which may be fine considering adding an empty one doesn't affect voting power.

Not guranteed to be empty necessarily. They may have skipped accounts and an account loaded later could contain value. Def seems like a follow up improvement to refetch on account add.
