fix: remove VARCHARs from Sales Invoice (#27136) (#27139)

Sales Invoice doctype is starting to hit row length limit as many
integrations add custom fields on this doctype. This is just a small
change to remove VARCHAR(140) fields and reduce row size wherever
possible.

(cherry picked from commit 8d116fb9ff)
