Small & mighty improvements

💜 We're always looking to improve your experience.

1. We improved the loading states and performance of the Account Intelligence pages. They load faster ⚡with pretty loading skeletons 💀so you get a sense of what's coming.
2. One of our developers found it VERY annoying when he'd start searching on the Accounts page, click on a specific account, then click back and lose not only his search but all other results. He's improved the experience so that you don't lose your search results when you switch between the Accounts page and a specific Account Intelligence page. You're welcome. 😎
3. 🔨 There was a weird thing where the background would darken when you clicked on a Filter in the Explorer search bar (it was not meant to be a modal). We fixed that for you.|
4. 🔨 There were a bunch of unclear error messages in the Rules user interface, making it difficult to troubleshoot rules on your own. Fixed it!
