[Feature]: Add hooks from staking module to keep live delegations synchronized with valsetprefs

[sunnya97]

Summary

Add hooks from staking module to keep live delegations synchronized with valsetprefs

Problem Definition

RIght now, if a user selects a stake squad in valsetprefs, but then does a direct staking module stake msg, their live delegations are out of sync with what's stored in the valset prefs module.

Proposed Feature

We should make it so that if they do a raw stake msg, it updates their valsetpref as well (or just removes it, so it falls back to the passthrough functionality of valset prefs module)

Updating is preferred, if simple
