Custom styles

added custom messiah colors and font to tailwind config

Alright, the messiah blue color looks great, I made a few changes for consistency:

• The CSS for the border of each SectionContainer had the border and the color attributes split up and an orphaned "messiah-blue-500" attribute that was not attached to anything. This was causing the border to appear light gray, which works, but I also added a shadow to this to bring it more in line with the header, which doesn't look as nice with light gray. So now the border is Messiah blue with a light gray shadow.
• I added hover: and active: to all buttons currently in use, we might want to replace these with the ButtonField component down the road to make this easier.
• I made the header have a messiah-blue background (if this was intentionally bright blue feel free to change it back or just let me know and I can do that as well).

I also did look into making the buttons messiah-light-blue to make it more in line with the Figma template, but it didn't seem to look as nice in practice. Perhaps it will look better once we have more buttons so that color is more in use, but for now, I left them as using the dark blue.
