[feature] report.ssh_key() formatting in Hosts

[KS-7250]

Is your feature request related to a problem? Please describe.

• Using report.ssh_key() for private keys in my tome grab_sshkeys always displays it in the hosts tab with no wrapping, causing it to go way off the screen when hidden. I have to scroll all the way to the right just to click the unhide button.

Used with (sample):

content = file.read("/root/.ssh/id_rsa")
report.ssh_key("root", content)

• Additionally, when viewed, it's not formatted in a generic private ssh key manner. When you copy+paste it into vim for example, it comes out all together separated by spaces instead of in a normal ssh key format. This forces the end user to split it by spaces and format the key themselves, costing time when grabbing many ssh private keys. I shouldn't have to do a bunch of .split()s and string manip to get a key that I can copy from Realm's Hosts tab.

• When pasted into vim:

Describe the solution you'd like

1. Wrapping for the Secret tab in Hosts whether content is shown or hidden by asterisks.
2. Support for formatting ssh keys, whether it be a separate function in eldritch or automatically.
3. Should be a copy button for credentials that copies them in a way that they can be pasted into a terminal. (ex. pasting an ssh key into vim for use)
