docs: README accuracy pass + modules quick start (audit group F)

The stale claims the audit pinned: seven wait strategies (was "six",
two places), test counts refreshed (~560 unit + ~210 integration),
mutual TLS is verified end to end in CI (the tls-e2e dind job - the
Remote row and the Known-gaps sentence said otherwise), and the
ConanCenter wording now points at the in-review PR
conan-io/conan-center-index#30600 instead of "planned right after
v0.1.0". Status gains the modules-layer bullet (on main; ships with
0.2.0), and Quick start gains a PostgreSQL module snippet - the 0.2.0
headline feature had no example. Version-specific bits (requires
0.1.0, the Status headline) deliberately stay until the release pass.

Opus review: SHIP; the one nit applied (gtest include in the snippet).
