Fixes error handling across wolfSSL example files, split into two commits by area:
Crypto/signature examples, 19 findings: F-1298 F-1302 F-1307 F-1712 F-1713 F-1719 F-1720 F-1721 F-1722 F-2093 F-3466 F-3472 F-3477 F-4131 F-4132 F-4600 F-5612 F-6286 F-6289 F-6536
TLS/DTLS/protocol examples, 14 findings: F-1296 F-1301 F-1706 F-2112 F-2893 F-2900 F-3223 F-3899 F-4121 F-4123 F-4127 F-4128 F-4603 F-4604
Fixed: unchecked wc_InitRng/key-init return values, NULL derefs from wolfSSL_get_error() on a NULL ssl, error paths that fall through instead of goto cleanup/return, fd/resource leaks on error, and writing unauthenticated plaintext to disk before AEAD tag verification in both AES-GCM and Ascon file-encrypt examples.
