OAuth Server Access Token field: Auto-select on click; mark read-only
Summary:
When looking at the Access Token you often probably want to copy it. While buttons are one way (that's for a followup patch), clicking into the text field is another user pattern.
Highlight the entire string in the text field when doing so.
Also do not allow writing into that field.
Same game as rP8447af89.
