chore: align public-facing assets with cameleer.io

Replace personal/internal references in shipped artifacts ahead of
institutionalizing the product. registry.cameleer.io becomes the public
endpoint for the npm package and repository URL; gitea.siegeln.net
remains the internal CI publish target. Mock seed-admin renamed from
"Hendrik Siegeln" to "Ada Sterling" across pages, audit log, RBAC
mocks, and ui-mocks; Java exception namespace switched from
com.cameleer3 to io.cameleer in the route detail mock.
