crypto(gov): submitting delegator vote proofs fail to verify

[erwanor]

Describe the bug
I am not able to submit a vote on any governance proposal on my local devnet because the delegator vote proof fails to verify.

$: cargo run --release --bin pcli -- -n http://127.0.0.1:8080 tx  vote yes --on 1
...
Error: status: Internal, message: "could not broadcast transaction: transaction pre-submission checks failed: a delegator vote proof did not verify: delegator vote proof did not verify", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc"} }

To Reproduce
Steps to reproduce the behavior:

1. Query the validator list
2. Delegate some penumbra to a validator
3. Create a signaling proposal: cargo run --release --bin pcli -- tx proposal template signaling and save it to signal.toml
4. Submit the proposal: cargo run --release --bin pcli -- tx proposal submit --file signal.toml
5. Check that the proposal is present: cargo run --release --bin pcli -- query governance list-proposals
6. Vote on the proposal: cargo run --release --bin pcli -- tx vote yes --on 0
7. See error

Expected behavior
The proof should not fail to verify during the pre-submission checks.

Additional context
It's possible that the proof uses the wrong balance commitment (unbonded amount or staked note) as input.

Reproducing on v0.59.0 leads to the following error:

Error: status: Unavailable, message: "error fetching notes: Invalid column name: asset_id", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc"} }

This was fixed by 907d6f854ddc98c829a0ea97ece4386f9e3b546b. You can do git checkout 907d6f854ddc98c829a0ea97ece4386f9e3b546b and run the commands with the fix.

I'm checking that the public inputs to the proof match those that we feed to the verifier, and I noticed that on one hand (proving) we use the balance commitment to the unbonded amount and in the other we use the balance commitment to the staked note. I think that what we want to do is have a commitment to the voting power at the time of delegation (i.e. unbonded amount).

Opened #2969 to fix this.
