Explorer displays incorrect voting power before vote

Nobody has claimed this yet.

### Describe the bug

When voting on a proposal with my Pixelfield orchestrator, the Explorer displayed my voting power as 69 LPT.

However, after submitting my vote, the vote percentage appeared to increase by approximately 0.4%, which would correspond to roughly 12,000 LPT based on the total voting power. This suggests the actual voting power used was different from what was displayed.
Rick suggested this may be a UI issue where the Explorer only displays the voting power directly associated with the wallet, while the vote counting also includes delegated stake attached to the orchestrator.

### To Reproduce

https://explorer.livepeer.org/voting/0x74479927117d4158b32c03d5400c14bdd7e6a46a
see voting power on right side

### Expected behavior

The voting power shown in the UI should reflect the total voting power that will actually be used for the vote (or clearly distinguish between wallet voting power and delegated/orchestrator voting power).

### Additional context

Start at the voting page linked in the issue and trace how the Explorer displays voting power before a vote versus how the submitted vote affects the percentage. Determine whether delegated stake attached to the orchestrator is included in voting. Done means the displayed value matches the power used for voting or clearly distinguishes wallet and delegated/orchestrator power.
