ResizableDirective started a drag from offsetWidth, which includes
padding and border, but writes the result to style.width. The hosts
are content-box, so the first move widened a padded host by its
padding plus border: 23px on the workspace categories panel, 1px on
the Favorites sidebar. Each drag also saved a width that much larger.
A drag now starts from the computed CSS width (the box style.width
sizes), falling back to the directive's own width when that is not a
length. Border-box hosts (live-layout and groups rails) are unchanged.

The workspace context panels and Favorites share one stored
`sidebar-width` but clamp it to different limits. Loading wrote the
clamped value back, so visiting Settings (max 400) cut a categories
panel widened to 520 down to 400; the saved width could only shrink.
Load now clamps for rendering only. Legacy alias keys migrate their raw
value, an unparseable value falls back to the default without a write,
and only a drag that changes the width persists — a click on the handle
no longer saves the clamped width either.
