PRISM v4.5

• Start a new job from any job's page. Every job's detail view now has a
  + New job button, so you no longer have to go back to the list first. The
  form opens with that job's settings (usually only the PR id changes), and
  Cancel takes you back to the job you were on.
• Ctrl+Enter starts the review. Once the PR id, working folder, region and
  repository are filled in, press Ctrl+Enter instead of clicking
  Start Prisming. It does nothing while anything required is still missing.
• Fixed: the model list could stay empty forever. The engine sometimes
  can't answer for a few seconds after it starts, and PRISM gave up on the
  first failure, leaving "could not list models" and an endless "Loading
  models…". It now retries, remembers the last good list, keeps re-asking in
  the background, and says what it's doing.
• Fixed: reviews failing with Agent not found: "pr-reviewer" when PRISM
  was started from a different folder than the project, on opencode 2.x.
