fix(ui): info icons show the button hand, not the text caret (Windows)

The settings info icons are role="button" spans with a text "i" glyph but no
cursor/user-select, so hovering the glyph gave the I-beam text caret on Windows
(Linux happened to resolve a pointer). Add cursor:pointer + user-select:none so
it reads as a button on every platform.
