Feature request: add UpdatePubKey function to https://test11.testnets.gno.land/r/gnops/valoper

Wrong pub_key registered — need UpdatePubKey function

What happened

During registration, I accidentally submitted the node_id pub_key (P2P) instead of the validator_key pub_key (consensus). Both keys share a similar prefix which made it easy to mix them up.

As a result, my validator is not signing blocks because the registered pub_key does not match the actual consensus key.

Details

• My validator address: g1e5sxezpafa8lcv5xu3nmw4plz30mnepq2wv9xs
• https://test11.testnets.gno.land/r/gnops/valopers:g1e5sxezpafa8lcv5xu3nmw4plz30mnepq2wv9xs
• Incorrectly registered pub_key (P2P / node_id):
  gpub1pggj7ard9eg82cjtv4u52epjx56nzwgjyg9zp0t2w0z50qfz9zc9vcld59p8f77pw052whd8w6rpksfqrk2rh877ycv0xm
• Correct pub_key (consensus / validator_key):
  gpub1pggj7ard9eg82cjtv4u52epjx56nzwgjyg9zqlfnw26wg5a6wph2k2cqhdwplq73nrckcz755e85yy047ykmlvhtdvw077

Both keys start with the same prefix (gpub1pggj7ard9eg82cjtv4u52epjx56nzwgjyg9z) and only diverge after that, making this a very easy mistake to make.

What I need

Either:

1. A new UpdatePubKey function added to the contract so validators can correct their registered pub_key — this would help anyone who faces this same issue in the future.
2. Or a manual correction of my registration by an admin (if that action is possible)

Notes

The current contract exposes UpdateMoniker, UpdateDescription, UpdateServerType, and UpdateKeepRunning, but there is no way to update the PubKey field once registered. Given that pub_key is the most critical field for validator operation, I think this is a gap worth addressing.

Thanks in advance!

Something like:

// UpdatePubKey updates an existing valoper's consensus public key
func UpdatePubKey(cur realm, address_XXX address, pubKey string) {
	// Check the valoper exists
	if !isValoper(address_XXX) {
		panic(ErrValoperMissing)
	}

	// Validate the new pub key format
	if err := validatePubKey(pubKey); err != nil {
		panic(err)
	}

	// Fetch the existing valoper
	v := GetByAddr(address_XXX)

	// Check caller is authorized (owner or auth list)
	v.auth.AssertOnAuthList()

	// Update the field
	v.PubKey = pubKey

	// Save back to the tree
	valopers.Set(address_XXX.String(), v)
}
