chore: ui enhancements

[jlangy]

This ticket was a bit of a grab-bag of things:

• Remove the sidepanel for edits, make it its own page
• More the URIs information into a modal
• Fix typo on landing page. It was not text, it was an image. So I broke out the svg into just the fish and squid and made html markup so that text is editable and adjustments are easier going forward, improves responsiveness too
• remove the "create realm" link from the top navigation

I also tried to add enhancements where things were a bit off, e.g I added a debounce to the user search and fixed an issue with the ministry/branch/division updates
