Pull request overview

This PR is primarily a formatting/readability refactor of the ObjectiveController.js React component, reflowing long lines and JSX into multi-line forms. It also makes two small functional/UI tweaks: removing the "Objective Controller" heading and changing the container/live-view sizing to use full width instead of fixed max dimensions.

Changes:

• Reformat multi-condition checks, arrow functions, and JSX props/children across the component for readability.
• Widen the root Paper to width: 100% / maxWidth: 100% and remove the LiveViewControlWrapper wrapper's maxWidth/maxHeight/overflow/background styling.
• Remove the <Typography variant="h5">Objective Controller</Typography> heading and clean up minor whitespace (e.g., trailing spaces on </Button>, double spaces in handleSwitchObjective(1, true )).
