fix(configurator): widen direct-order wizard modal so line columns breathe

User complaint: the direct-order wizard's line table was crammed —
"Primary Treatment" showed as "Primary T..." and "Serial Number"
as "Serial Nu..." at the default Odoo modal width (~992px).

Added a dedicated stylesheet that targets the wizard via a new
o_fp_direct_order_wizard class on the form element. The modal
dialog containing the wizard now opens at min(1600px, 95vw) —
wide enough for the 10+ columns (Part, Primary Treatment, Process,
Thickness, Serial Number, Qty, Unit Price, Subtotal, Part Deadline,
WO Group) to fit without truncation on typical desktop displays,
while still adapting to narrower screens.

Also nudged per-cell horizontal padding from Bootstrap's default
to 10px left/right so the columns have a bit more breathing room
inside the wider table.
