Ruben FiszelandClaude Opus 4.8 3bfd5eb710 fix(security): honor postgres sslmode verify-ca/verify-full (CWE-295)
PgDatabase::connect_inner lumped require/verify-ca/verify-full together and,
whenever no root_certificate_pem was configured, set danger_accept_invalid_certs
+ danger_accept_invalid_hostnames — so a resource explicitly configured with
sslmode=verify-full (or verify-ca) silently got an encrypted but completely
UNVERIFIED connection (MITM-able).

Now verification follows libpq semantics:
- require:     encrypt only, no certificate verification (unchanged)
- verify-ca:   verify the certificate chain, but not the hostname
- verify-full: verify both the certificate chain and the hostname

A configured root_certificate_pem is still added to the trust store for all
three modes.

Note: a verify-full/verify-ca resource whose server cert does NOT chain to a
trusted root and that did not provide root_certificate_pem will now fail to
connect — which is the correct, secure behavior (such a config was previously
accepting any certificate). Those should provide root_certificate_pem or, if
encryption-without-verification is genuinely intended, use sslmode=require.
