Local extensions plus a crash fix, carried as a port patch.

Bug fix (upstreamable): query the days/search endpoint for the authenticated
user instead of a user key hardcoded in the source.  Without it the response
is empty and the tool aborts with "list index out of range".

Local feature: derive each working day's required hours from a configurable
contract value (daily_hours) instead of a hardcoded 8, and shorten a working
day by preholiday_reduction when the next calendar day is a Tempo HOLIDAY.
Tempo is used only as the holiday calendar; the work scheme is not required.
