docs: refresh security docs and fork references

Update the STS, security, select, and Docker documentation to reflect the recent hardening work, including LDAP STS throttling details, OIDC JWT verification changes, and the new pgsty-specific security policy and advisory index.

Rewrite repository and raw-document links that still pointed at minio/minio so the docs consistently reference pgsty/minio instead.

The core idea is to keep the documentation aligned with the fork's actual security behavior, ownership, and upgrade guidance without mixing in unrelated code changes.

+- CSV input records larger than 1 MiB are rejected with `OverMaxRecordSize`. For line-delimited JSON, the same limit is enforced on the non-`simdjson` fallback path; builds that use `simdjson` continue to rely on the parser's own streaming behavior.
 - CSV input fields (even quoted) cannot contain newlines even if `RecordDelimiter` is something else.
