splitsec2andCaliBrain cb72ce807c Merge commit from fork
A user could set any value for their own overridable settings through
PUT /api/users/me. DESTINATION and DESTINATION_AUDIOBOOK accepted any
string, so a download (including one an admin fulfilled for that user)
could be written to any directory the container can reach, and
get_destination created it on demand.

A user's own destination must now resolve inside the global one (with
{User} expanded on both sides). Absolute paths outside it and any ".."
segment are rejected at save time, and get_destination applies the same
check when the path is used, so a stored or hand-written value outside
the global destination is ignored with a warning and the global
destination is used instead. A relative value is taken relative to the
global destination.

Other self-service values are checked as well: select fields must use
one of their options, EMAIL_RECIPIENT must be a plain address (the same
check the orchestrator and the downloads tab use, now shared from
request_helpers), and Grimmory library and path ids must be non-negative
integers. Admin saves on a user's behalf are unchanged.

The self-service 400 response now carries a message line so the reason
reaches the user in the toast.
