fix: let the path picker's error status wrap (release review)

The cases-folder refusal grew to 143 characters, and the status line is one
line with an ellipsis and no title, so at 513px on desktop it ended at "or
make the case with Ad..." and lost the instruction. .path-picker-status.error
now wraps: 2 lines on desktop, 4 on a phone, measured clear in Chromium at
both, and it covers the picker's other refusals too.

Tests: a pin on that rule (fails without the fix), and the option check now
reads each picker's whole options object instead of a fixed 400 characters,
which stopped short of the container-workdir picker's 829. Retitled to say
what it checks: Create New has the flag too.
