Explore enhancement - Add State of Bitshares Network tab

**Is your feature request related to a problem? Please describe.**
The number of platforms being built on top of Bitshares has and will continue to increase rapidly. Jumping from one platform to the next can be a chore, and even un-secure just trying to make comparisons or exchange.

**Describe the solution you'd like**

Clicking the tab takes the user to a list (similar to CryptoKong's Ecosystem List but looks like the GIF below ) which entails projects built on Bitshares providing any user a one page view of real time trading. It would be nice to incorporate both send and receive broadcasts but maybe not possible.

Each project could be click-able taking the user to that DEX, website, discord, etc or all.

If for nothing else, it provides an impressive network activity report for evaluation, comparison, usage, and other metrics.

**Additional context**
GIF captured from coinlib.io (assumingly Bitshares on reflective exchanges). Having this data on our Explore would also be nice but I understand the need to keep it light.

Start by locating the existing Explore view and reviewing the proposed State of Bitshares Network tab shown in the issue images. Clarify the project list, real-time trading data, broadcast support, and external links before implementation; done means the tab provides the agreed network overview without compromising the interface’s lightness.
