feat!: regenerate SDK from updated Timeweb API spec

[release-plz-yew-nav-link]

The upstream Timeweb Cloud OpenAPI specification changed.

This pull request was opened automatically: it vendors the new
spec, regenerates src/apis and src/models and refreshes
the README statistics. The regenerated SDK builds and its tests
pass.

cargo-semver-checks reports breaking changes (or could
not complete); this pull request stays open for review.
