🔨 Switch grapher exports to use CF worker

[ikesau]

Resolves #4093 and #3661

Supersedes #3746

Changes

• Switches all references to /exports/ to use our dynamic thumbnails instead
  • Except the mockSiteRouter view in /admin/charts
• Removes code that baked graphers to /exports/
  • Some charts in country profiles will no longer load in the NoJS version of the site because their slugs have updated but formatWordpressPost isn't checking redirects. We could:
    1. Fix this in the code
    2. Update the country profile templates
    3. Not fix it
• In all thumbnail imgs where applicable, switches the image extension from .svg to .png, to ensure webfonts always show correctly.
