feat: Extract certificate details

[saltiyazan]

Description

• Improves the code to extract certificates
• Improves the code to compare certificates
• Display certificate details

Both certificate and csr details are displayed, as there is no guarantee that those are equal.
Discrepancies between csr and cert fields are highlighted in red.
The details are responsive and they go into one column on small screens.
The expiry date is coloured green, it turns red when we are within one day into expiry and beyond.

I really like how it looks. I especially like that if the common name is very long the certificate details wrap.

There are still some suggestions though.

I think we can pass on the highlighting for now.
