Add missing TLS signature schemes

This commit fixes a few places where new signature schemes were not added:

1) It adds ECDSA with the Brainpool curves for TLS 1.3 (0x081a, 0x081b, and 0x081c) to get_server_certificate(), certificate_transparency(), and prepare_tls_clienthello().

2) It adds rsa_pss_pss (0x0809, 0x080a, 0x080b) to certificate_transparency().

3) It adds the signature schemes for EdDSA (0x0807, 0x0808) and ML-DSA (0x0904, 0x0905, 0x0906) to certificate_transparency().
