DESCRIPTION OF ISSUE

Iconography is missing lots of tx methods. In addition, some are not clear to users based on internal feedback (for example Start undelegate)

consensus.Meta
keymanager.PublishEphemeralSecret
keymanager.PublishMasterSecret
keymanager.UpdatePolicy
registry.DeregisterEntity
registry.ProveFreshness
registry.UnfreezeNode
roothash.Evidence
roothash.SubmitMsg
staking.Burn

and new types added in v24.0 (not handled by Nexus yet, but we will need it anyway)
keymanager/churp.Apply
keymanager/churp.Confirm
keymanager/churp.Create
keymanager/churp.Update
vault.AuthorizeAction
vault.CancelAction vault.Create

@buberdds imo worth revisiting, but perhaps better to do this after the UI framework has been chosen, WDYT?
