Fjord Token Staking

Summary :

• there is no explicit handling of penalties or redistribution of penalized amounts to other stakers.

Vulnerability Details :

• This means that the penaltyAmount, instead of being reused or reallocated
  within the contract, simply reduces the total available
  rewards (totalRewards).https://github.com/Cyfrin/2024-08-fjord/blob/0312fa9dca29fa7ed9fc432fdcd05545b736575d/src/FjordStaking.sol#L650-L651

  As a result,
  the penalized amount are essentially "lost" and not redistributed
  or used elsewhere,
  which might not be the intended behavior

Impact :

• This could lead to a faster-than-expected depletion
  of the reward amount, especially if multiple users claim early and penalties
  are applied often.

Tools Used :

• Manual code review

Recommendations :

• Add a function to redistribute penalties amount to remaining stakers.
