feat: Canvas Settings Page

[forestileao]

Changes:

Added Canvas Settings page with the following changes:

• Change name/description (note that rename doesn't work now)
• Turn on/off versioning
• Let's not call it sandbox mode
• Whatever is in org settings should be a default state for new Canvases
• Fix the links so they are actual links and not JS
• deleting a Canvas should not try to open it

👋 Commands for maintainers:

• /sp start - Start an ephemeral machine (takes ~30s)
• /sp stop - Stop a running machine (auto-executed on pr close)

Should we add some tests for this? 🤔
Doesn't feel right that we haven't covered it at all.

@shiroyasha I will add e2e tests

Updated to correct behavior:

Org canvas versioning ON => all canvases effectively ON.
Org canvas OFF => canvas can still be ON/OFF
