Improved Payment UI

We have made changes to the payment ui to make it more user-friendly and easier to use
invoice based orgs can now also connect Polar to their account (At the same time)
Added option to add text inside the payment plan component columns
Fixed a bug where the pricing plans border and post a job button in dark mode were always using light mode
We are now showing the payment plan title
We have reduced the size of the currency symbol in the pricing plans because this is a known way to have some impact on the conversion rate
We have improved the UI of the payments page by adding list tabs and a single select option with all pricing options. This makes it easier to see all options and less cluttered
