Add pages

Judges a list of addresses and, unless `dryRun` is true, adds the accepted ones as pages and starts reading them in the background. The rules are the dashboard's: an address must be https and on the site's own origin, it is normalized (fragment, `utm_` parameters and a trailing slash removed), a repeat is ignored, and above 50 non-empty lines the whole request is refused with `invalid_request` and nothing is created. The answer names the outcome of every line. The answer is `202` when a read was started: read the progress from the pages. It is `200` for a dry run, and when no line was accepted.

curl -X POST "https://example.com/api/v1/sites/string/pages" \  -H "Content-Type: application/json" \  -d '{    "lines": [      "/products/trail-shoe",      "https://shop.example/collections/summer"    ],    "dryRun": false  }'
