Subject: [PATCH] x509_crt: Zero-initialize mbedtls_x509_time at declaration
'mbedtls_x509_time now' is a local struct variable. passing an uninitialized local as a const *
argument is UB-risk, since the callee is not
allowed to write into it.
Clang-21 got stricter about const pointer arguments finds it and flags it.
zero-initializing ensures all fields are defined.
