Send validator payment on actions that would modify reward distribution #11211

Description

Some functions would modify the amount or payment split in EpochManager.sendValidatorPayment. This PR adds a call to sendValidatorPayment before such modifications occur to ensure the payment split is deterministic after epoch processing.

The functions are:

  • Validators._deaffiliate (called by affiliate, deaffiliate, and forceDeaffiliateIfValidator), which would change the group the validator is associated with, thus the group that would receive the group portion of the payment
  • Validators.updateCommission, which would change the split between validators and group.
  • Accounts.setPaymentDelegation, which would change the split between validator and beneficiary (and/or who the beneficiary is). However, since this is a voluntary payment from the validator, the protocol does not need to ensure this stays the same, so we can choose not to use this mechanism here.

TODO:

  • Do this for Validators.setPaymentDelegation

Other changes

  • Removed allowOnlyL1 from a few functions
  • Function ordering for linter

Tested

Unit tests.

should this avoid the call completely in L1?

sendValidatorPayment should probably revert if the epoch system is not initialized

should there be an isL2 check in this function as well? this would avoid going thru the loop.

Alternatively, it could be implemented when the function is used.
