RE: HivePulse.app: Just pushed some new improvements and fixes

Here are some touches implemented on the received feedback:

1. KE Ratio tooltip: replaced hover-only tooltip with click/tap toggle. Hope this is more mobile-friendly.
2. In Search history dropdown: remove button always visible and added onTouchEnd alongside onMouseDown for mobile touch support.

I have commited the changes on the server so they should be live, even if I didn't do any formal testing for mobile.
I will check it as well on my mobile. Thanks again!
