UI - Updates to framework for Individual Form

[mstanton1]

• Individual's Details becomes a section header and address label and birthdate label move to the left (instead of on top)
• Tax Details section is removed and Canada Revenue Agency (CRA) Tax Number and Tax Residency label are moved to the left in the Individual's Details section
• Spacing between sections is adjusted so there is slightly more space between completely distinct sections, versus smaller spaces when the details are similar in nature (details in design). 40 pixels between discrete sections, 20 pixels between related sections, border or 1 pixel break between pieces within a section such as between birthdate, citizenship / permanent residency, cra tax number etc.

@hfekete couple of spacing issues with the section headers (in general) - it's feeling a bit tight, can we make the spacing like this?:

And then with the larger sections that have a header the corners of the white box should be rounded at the top but then no radius in the subsequent inner sections until the bottom

@hfekete just noticed this weird spacing happening also with the button running into the top of the form:

And i assume that the date of significance will get moved when you update that component?
