SMB offer letter updates

Comments for test Offer letter rendering:
1. Font for fields and template is diffrent should be the same
2. Gaps after inserted fields - should be smooth
3. 2019-09-02 - should be converted into correct region format. For US it is MM/DD/YYYY
4. semi-monthly - id to be converted into human readable string
5. fifteen_and_last_day - id to be converted into human readable string
6. Roles and Responsivilities... - we are planning to send multiline text with lines delimited by \n character. Please test multiline.
