Subject: [PATCH] fix: guard Icon src against non-function values to prevent
 crash

Add defensive check in folds Icon component so that if src is ever
undefined or non-function (root cause unknown, possibly data-dependent),
the SVG renders empty rather than throwing and crashing the whole app.

Also adds postinstall script to re-apply the patch after npm install.
