Anyway , why would district stock ever run through to tilbury anyway?

1910 - 1939 there were through trains between Ealing Broadway and
Southend, electric-hauled over the District between Ealing Broadway
and
Barking, and changing engines there.

Short clerestory roofed electric engines

Long clerestory-windowed Christian churches, i've heard of; how does a
clerestory roof work?

A raised centre section to the roof, in the side of which may be either
glass windows or sometimes ventilator louvres. They were a common feature
of 19th century carriage design.- perhaps as a means of 'borrowing' light
for the middle of compartments.

Having thought about this - (a) was this before they'd thought of
skylights and (b) what was the point of putting such a thing on the
engine, rather than the passenger carriages?

Skylights are quite difficult to make water-proof (our old Citroen BX with
indoor swimming pool was proof of that..).
As to why such things were fitted to an electric loco? They may have been
there to illuminate the internal workings or, perhaps more likely, as
ventilation.
