fix(files): not found page

[ChayanDass]

• fixes Missing error when user tries to open missing file #2453

Bug

FileNotFound was not displayed because of an early path check:

if (files.path && filesPathInfo.path && files.path !== filesPathInfo.path) {
  return null
}

When files.type === 'not-found', the paths differ, causing an early return.

##Fix

Render FileNotFound before checking for stale paths. This ensures missing files show the correct component.

Triage note:

• this is likely handled bit more extensively in feat(files): resolve paths before inspect and support protocol URL #2465
• tbd if we need this if that one lands
