[IMP] point_of_sale: show opening and closing note as multi line

before this commit, on printing sales report from pos ui or
from the backend, the opening note and closing note in the
report is shown as single line text, even though user enter
the input in multi line.

* point of sale -> reporting -> session report

after this commit, the opening and closing details in the
same way in which user enter the input also fixed a typo
opening session note
