Feature/wikidata id routing

[Greenheart]

• Update routing to handle wikidataId to allow backwards compatible URLs.
• Improve error handling and make it easier to search for a company page to find it even if the URL for some reason was broken.
• Improve layout for error states to make it look consistent with the rest of the page.
• Add memory caching for loading companies to reduce number of requests to the API, while still keeping it fresh.
• Other minor fixes for icons and layout
