Fill missing company areas with the domain and favicon

[MineGene]

Issue Details

Having missing company data makes the column feel incomplete.

Proposed solution

In the absence of data consider simply placing the domain and favicon for that domain there.

Alternative solution

Find a way of more reliably adding company data that doesn't have such strict rules such as the ones in the companiesdb, perhaps something the community can contribute to much more easily from AdGuard DNS itself.
