[WIP] Fix Swift compile error with optional Date unwrapping

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Swift compile fails during CI with: "value of optional type 'Date?' must be unwrapped to a value of type 'Date'" in Sources/prosign/views/CertificateView.swift. The root cause is that certExpiries is declared as [String: Date?], so a lookup returns an optional Date? (i.e., Date??). The code passes that lookup directly to expiryDisplay(for:) and force-unwraps expiry in certificateBackground(for:), causing a compile error and unsafe force-unwraps.

Make the following safe, minimal changes to fix the compile error and avoid force-unwraps:

1. In certificateContent(for:), unwrap the dictionary lookup and the inner optional Date before calling expiryDisplay(for:). Replace the block

   if let expiry = certExpiries[cert.folderName] {
   expiryDisplay(for: expiry)
   } else {
   Text("No expiry date")
   .font(.caption)
   .fontWeight(.medium)
   .foregroundColor(.secondary)
   }

with:

if let expiryOptional = certExpiries[cert.folderName],
   let expiry = expiryOptional {
    expiryDisplay(for: expiry)
} else {
    Text("No expiry date")
        .font(.caption)
        .fontWeight(.medium)
        .foregroundColor(.secondary)
}

2. In certificateBackground(for:), remove force-unwrap and safely bind the inner optional. Replace:

   guard let expiry = certExpiries[cert.folderName], expiry != nil else {
   return Color.clear
   }
   let now = Date()
   let components = Calendar.current.dateComponents([.day], from: now, to: expiry!)
   let days = components.day ?? 0

with:

guard let expiryOptional = certExpiries[cert.folderName],
      let expiry = expiryOptional else {
    return Color.clear
}
let now = Date()
let components = Calendar.current.dateComponents([.day], from: now, to: expiry)
let days = components.day ?? 0

No other functional changes are required. Keep file formatting and surrounding code unchanged. Commit the change and open a pull request with a concise title and description referencing the CI failure and this fix.
