Enhanced Outlook UI

Made since Stanford uses Microsoft/Outlook for all student emails.

Changes this extension makes

1. Restores Chrome’s normal page pinch zoom in Outlook.
2. Keeps normal sideways scrolling available when the page is zoomed in.
3. Makes the Archive button wider and ensures icon-only versions have one clear label.
4. Adds −/+ controls and -/= keyboard shortcuts for scaling an opened email's content from 80% to 160%.
5. Adds saved popup toggles for every feature and the extension as a whole.

The extension runs only on outlook.office.com and outlook.cloud.microsoft. It requests only extension storage for saving the on/off setting; it does not send email data anywhere.

The toolbar icon is a cardinal-red mail mark with a red plus, representing Outlook enhancements.
