Control content of offer objective and experimental design during offer pfd generation

[jenniferboedker]

Is your feature request related to a problem? Please describe. Currently there is no check for the length of the offer description (objective, exp. design,..). Since there is also no spacing method accounting for a high amount of content implemented as of yet, this can lead to an overflow into the footer section of the first page.

Describe the solution you'd like The offer description content should be properly spaced over multiple pages via pagebreaks if it's too long to fit on a single page.
A possible solution could be to count the number of characters in the provided content and set spaces accordingly.

Describe alternatives you've considered One could also think of a solution that restricts the content for the offer objective, to ensure that it fits to one page. Currently the hard limit is set by the database column (2500 characters)
