Import new job from URL and/or bookmarklet

[sethetter]

To ease the process of adding jobs to the job board, we should have ways to quickly fill in some details on the new job form.

• A GET endpoint that accepts a URL, and optionally other pre-filled information, and redirects to the new job form with that information pre-filled
• If only the URL is provided, attempt to scrape the job title and company from the title or other information
  • Lots of ways we could go about this
    • Implement deterministic info scrapers for known application systems (ashby, etc).
    • Use an LLM, or some LLM-based scraping service
