[Type of FI] Update page content

[meissadia]

Close #532

This PR has transformed into a few smaller header updates and some code cleanup:

• Update institution (section header)
  
• Provide type of financial institution (header)

Updated spacing between other and helper text

@meissadia Unintentionally and coincidentally, I included all the changes from this PR and integrated in my PR: #566 since I was overhauling the Error header with content passes.

Please check that PR and see if we can close this PR.

@shindigira Think I've cleaned out all the duplicated code bits.

I'm not sure what to do about FormFieldsHeaderError. Github says it's new but my local git history says it was added 9 months ago. I don't see any references references so it's probably safe to delete, but I just want to be sure I'm not over looking something.

Awesome! Just minor stuff and we can get this in.

@meissadia I put all of the inline errors and associated form header errors in one place -- formErrorHeader.data.ts.

Thanks for sorting through all the changes.

[meissadia]

@shindigira Alright, now it's looking quite clean. Thanks for the feedback!
