fix: rename docked queue panel setting (#9620)

## Summary

Rename the `Comfy.Queue.QPOV2` settings label to `Docked job
history/queue panel` to improve searchability/discoverability in the
settings UI.

## Changes

- **What**: Updated the visible setting name in the core settings
definition and the English locale string.

## Review Focus

The change is intentionally limited to the display label. The persisted
setting key remains `Comfy.Queue.QPOV2`, so existing user configuration
is preserved.

## Screenshots (if applicable)
