Improve linear compatibility with Safari, run button metadata (#8107)

I downloaded the oldest webkit based browser I could find after reports
of display issues. The changes here cause some minor styling tweaks, but
should be more compatible overall. A quick list of fixed issues
- Center panel placeholder had incorrect aspect ratio
<img height="500" alt="image"
src="https://github.com/user-attachments/assets/b75e3c49-20d9-4d6e-bca4-95cc8a73f821"
/>
- Image previews had incorrect aspect ratio (But the other way around)
<img height="500" alt="image"
src="https://github.com/user-attachments/assets/b8ebc58e-2655-41f8-a3b4-70ba65940612"
/>
- On mobile, output groups would flex incorrectly, resulting in a large
gap between them
<img height="500" alt="image"
src="https://github.com/user-attachments/assets/ed7e8e43-c34e-4ffc-a3ee-126b1a2ef4e0"
/>



Also moves the run button trigger source to a new 'linear' type
