[feat] transfer responsibility / "Verantwortlichkeit übertragen"

[eins78]

for Resources: MediaEntry, Collection

story

As a Madek User, I am the initial "Responsible" (responsible_user) for all Resources that I have created.
Technically, Resposibles have implicit rights for all managed Permissions and are the only Users allowed to delete a Resource. They are also "responsible" for the associated content and files in a legal sense.
Because there always has to be exactly 1 Responsible for each Resource, it can only be transfered to another User in 1 step.
Because the "old" Responsible would lose the implicit Permissions, they can select the ones they want to retain in the same step (usually at least view & download).

Those departments defined as their submissions process that the last step is the transferal
of the responsibitly to their designated administrator (secretary).
