feature: app refactoring

[anton-karlovskiy]

• Get rid of redux use cases for tab switching in favor of query parameters.
• Clean up AccountModal by using tailwindcss.
• Add Tabs component (basic level).
• Clean up according to the code convention.
• Create reusable hooks for manipulating query parameters.
• Fix minor bugs

@nud3l I think this PR domonstrates how much code we can reduce by not using Redux. :)

Note that passing a query parameter that's not in the TAB_TYPES object displays an empty modal. Maybe it's better to default to the issue tab, also setting the parameter value

You probably didn't touch that code, but I'm getting two runtime errors just by browsing the app.

• One is in src/App.tsx, where you need to import Big from 'big.js';
• The other is in src/pages/dashboard/components/collateral-locked.tsx, where fetchCollateralLastDays has an unhandled Promise rejection

The "App" and "Dashboard" sections used to take a rather long time to load and now they're super snappy. This was done in many other PRs as well, but just wanted to say great work!

Could you please help them out by making changes to this PR? Or code suggestions, please.
