feat(web): add change-compute button on idle notebook rows

[0x0f0f0f]

Summary

• Add a Cpu icon button next to each idle notebook’s overflow menu so editors can change compute without opening the menu.
• Keep the existing overflow action when a session is running (and when the inline button is hidden).

Test plan

• With multiple compute profiles and overrides enabled, hover an idle notebook row and confirm the chip button opens Change compute
• Save a new profile and confirm the notebook’s stored profile updates
• With a running edit or app session, confirm the chip is hidden and Change compute… remains in the overflow menu
• With a single profile or overrides disabled, confirm neither the chip nor the menu item appears

there are a ton of buttons in the dropdown. and im not sure what should/shouldn't be promoted outside. i dont imagine this is a common one. any reason to make this prompted as its own button?

launching a lot of GPU notebooks, just found it a lot of clicks to change the runtime every time a notebook is launched, but feel free to close!

@0x0f0f0f how are you creating these notebooks? Can you create them with GPUs to begin with? Is something reverting it back to an old computer profile?

@mscolnick they are pulled by the git app integration

once you set the GPU profile, does it change back? I'll make it so adding the new git-backed notebook lets you choose the computer and container

I'm trying to make it fetch automatically all notebooks in a repo, (and possibly in all repos from an org) into a project. So claude attempted this via CLI iirc. It doesn't seem to be changing back though
