uiux(Communities): various community profile popup ui fixes

This commit changes a bunch of things related to ui bugs in the community
profile popup. Fixes include:

- Removing the `Delete Community` option since this functionality isn't implemented yet
- Changing the color of the menu item's icons in dark mode to be blue
- Doing the same in the memberlist popup
