In this PR:

• get rid of catchall [[...all]] route in the root Get rid of catchall route #800
• all urls like coords feature (/50.1,14.1) and shortener (/xyzn) are kept, see rewrites in next.config.mjs
• Experiment: add static 404, which is routed by CDN itself, without the need for paid "function invocation"
  • lets see if this makes any difference :-) then switch off this experiment.
  • It works only for HTTP request to Vercel, on dev/while clicking in APP, the internal 404 may be rendered
  • WARNING: unfortunately I wasn't able to send HTTP status 404, so the page just have meta-equiv=noindex to prevent bots from indexing it

Expectation

All these red-marked paths should disappear from umami logs of "SSR requested paths". For last 30 days it means 20% out of 79k tracked SSRs. I still wonder where are the 800k function invocation reported by vercel. Lets see if it moves down also by 20%.
