fix(stash): guard nip44 getter to prevent crash when no signer/extension

Browse source 
Some signers throw "Browser extension not available" when the .nip44
getter is accessed rather than returning undefined. Wrap the check in a
try/catch so useStash never throws on mount for logged-out users or users
with signers that don't support NIP-44.
