Fix alignment of text in the plain-text emails

[theskumar]

Due to djhtml the emails templates where formatted with indendation. That lead to alignment also being present in the plain-text emails.

This was an unintentional behaviour that this PR fixes by adding {# fmt:off #} markers in the email templates so djhtml won't format them

Test Steps

• [ ] check the alignemnts of the paragraphs of different emails sent.
