As a user,
I want to know on which chains Schemas are available,
So that I know if it's missing for my specific use case

---

Currently, Schemas are accessed at https://explorer.ver.ax/[CHAIN_NAME]/schemas/[SCHEMA_ID].
Now that we are moving to a chain agnostic approach, the URL will be https://explorer.ver.ax/schemas/[SCHEMA_ID].

Detail page

On the detail page (https://explorer.ver.ax/schemas/[SCHEMA_ID]), we should display the exhaustive list of networks where this Schema is available. This list is a list of logos + tooltips, when hovering the logos, with the chains names.

Table view

On any table view (Search results + https://explorer.ver.ax/schemas), the logos should be displayed in small on the same row. Up to 4 logos, and if there are more chains, add a + x networks.
