Unable to initiate unbonding when bonded amount is below minNominatorBond

• fix: allow unbond/unstake for any user with bonded funds, not just active nominators #2874
• feat(fix): Bond checks isBonding, disallow new nominator if bonding or nominating already #2878
• feat(refactor): Introduce useBondActions hook, tidy up bond logic #3012

I believe this is a pallet-side limitation whereby a user cannot unbond if their bonded amount is less than min_nominator_bond, and not a limitation of the dashboard. The conditional statement and resulting pallet error can be found here:

If a user finds themselves in this predicament they need to chill first. They should be able to do this by hitting Unstake and submitting the transaction.

With that said we can make this edge case clearer in the dashboard by providing instructions in the screenshot warning & a link that replaces the modal with the Unstake modal.

Note: Can also resolve #2333 by doing this

Hi @rossbulat. The account used in the example screenshot was not actively nominating. Additionally, I was able to successfully simulate the unbonding of the bonded funds using Chopsticks. Could you please review the issue?
