0f035c1 RPCConsole::updateDetailWidget: convert strings to translated strings (Jon Atack)

Pull request description:

  - fixups from bitcoin#206 review feedback (thanks!), see commit message for details
  - hoists repeatedly used translatable strings to the `RPCConsole` class for reuse

ACKs for top commit:
  hebasto:
    re-ACK 6242bee
  Talkless:
    tACK 6242bee, tested on Debian Sid with Qt 5.15.2. I see "Ban for.." translated to my native language as before, "To/From/Yes/No" are not but that's expected, as `.ts` files are not updated.
