[ui_ssl_tls_improvements] coopr.sh and server.js imrovements

coopr.sh improved to show correct link in case of https startup. ui server.js improved to add tls data on every request.
:-1: this is bad, 3x `readFileSync` - is blocking

`updateRequestOptionsWithTls` is called in `getEntity` which is all over the place, so this would happen virtually for every request, possibly multiple times! I know this is the old UI but still...

TLS creds must be read from disk on app startup and then cached in memory.
