fix(app): trim the folder hint and label the memory field by its unit

The folder hint ended on "and the agent edits files in them without asking",
which reads as a warning at the moment someone is picking a folder — and the
permission model is a property of the sandbox, not of this field. Dropped, and
the surrounding em-dash aside folded into the sentence so it does not read as
though something was cut out of it.

"Memory GB (default 4)" put the unit on the label and left the default looking
unitless; "Memory (default 4 GB)" reads as the quantity it is.
