Text clipping/overflowing on show location screen

[crsdc]

Per report from CF, something about this screen doesn't look right on at least one variety of iPhone.

Note this screen intentionally looks very different to others in the app as it is designed to be held up in front of a camera to assist with documenting evidence. However, it should not clip or overflow.

So far unable to reproduce so awaiting further info from CF, specifically:

• please let me know which kind of iPhone you are using (Settings > General > About > Model Name)
• screenshot would be very helpful

Info since received from CF. Part of wider issue of text sizes and clipping, so rolled into #24
