Backend returns {"tasks": [...]} and {"logs": [...]} but TaskTab and
LogTab stored the raw object and called .map on it, throwing
'l.map is not a function' the moment a user opened the Tasks or
Logs tab. Unwrap via Array.isArray check (also covers theoretical
bare-array responses).
Regression test for TaskTab covers all three response shapes:
wrapped object, bare array, and empty.
