feat: allow to resolve local views of remote things

basically any id prefixed with + will be:
 * prefixed with 'https://'
 * have all '@' replaced with '/'
 * not be normalized with local domain patterns
thus allowing to look up kind of any url in our db

this is kinda reinventing the wheel, but i really don't want to have
local-only ids and would much rather have a local-only way to display
them, because at least everyone can understand it and look up anything
remote easily
