A few inconsistent strings in the Angular i18n login screens

[Jane Sandberg]

In Open-ILS/src/eg2/src/app/staff/login.component.html, the strings "Sign In" and "Sign in" are both used (one with a lower-case i, the other with an upper case one). Let's choose one and stick with it.

Similarly, Open-ILS/src/eg2/src/app/staff/login.component.html uses "Username" and "Password" for the placeholder text, but Open-ILS/src/eg2/src/app/staff/share/op-change/op-change.component.html uses "Username..." and "Password...". Let's get rid of the "..." so that translators have 2 fewer strings to translate.

I'll grab this and knock it out today.

I'm thinking "Sign In" looks a bit better as a standalone string, aesthetically.

Thanks, Sam! When I go to that link, though, I don't see your commit. Could you please try pushing your commit again?

Does that work? They just upgraded our work computers, and this is my first push to Evergreen since the changeover so I'm hoping everything worked normally.

I'd forgotten the important step of actually doing the commit locally.

Thanks, Sam! I'll take a look.

I've confirmed that this works well. When I run `npm run export-strings`, the resulting messages.xmb file no longer contains those duplicate strings. Pushed to master, rel_3_5, and rel_3_4.
