Context:
On self-hosted instances, some places in the code rely on the fact that we resolves public domains while being behind reverse proxies. This leads to cases where features are not available, such as the "Duplicate document" one.
Bugs that are solved - n self-hosted instances:
Impossible to open templates and tutorials right after having converted them;
Impossible to submit forms since version 1.1.13;
Impossible to restore a previous version of a document (snapshot);
Impossible to copy a document;
Solution:
Introduce the APP_HOME_INTERNAL_URL env variable, which is quite the same as APP_DOC_INTERNAL_URL except that it may point to any home worker;
Make /api/worker/:assignmentId([^/]+)/?* return not only the doc worker public url but also the internal one, and adapt the call points like fetchDocs;
Ensure that the home and doc worker internal urls are trusted by trustOrigin;

Summary:
The new "copyDoc" query parameter on the login page sets a short-lived cookie, which is
then read when welcoming a new user to copy that document to their Home workspace, and
redirect to it. Currently, only templates and bare forks set this parameter.
A new API endpoint for copying a document to a workspace was also added.
Test Plan: Browser tests.
