ref(insights): Refactor Seer Analysis sidebar component in the Web Vitals page overview

[edwardgou-sentry]

• Removes the Run Seer Analysis button from the Web Vitals page overview side bar
  • Web Vitals issues are no longer expected to be created manually by the user.
  • Deleted a bunch of hooks that are no longer in use
• Simplifies the logic for displaying Autofix suggestions in the Web Vitals page overview side bar
  • No longer contains logic to handle pending issue creation/autofix running state, since we no longer allow manually initiating autofix runs from the ui.
  • Updates to fetches issues and complete autofix runs once on load and without polling.
  • Pages that do not have existing issues and autofix runs will display no seer data in the sidebar
