Add post: A Read-Only NocoDB Dashboard for a Database on Another Machine

EN + ZH twins. The recipe for pointing NocoDB at a MySQL/MariaDB database on another machine: the Docker SNAT source-IP trap (the DB sees the host IP, not the container IP), a SELECT-only grant restricted to that one host, the async source-creation API with no job-status route, the auto-sync that makes a manual table step unnecessary (and the create-table route that makes junk tables), and what a read-only source costs (no metadata edits, UTC-labelled DATETIMEs). Also adds the og-gen TERMINALS and banner-gen BANNERS entries for the slug (keeping the sibling session's entries untouched) and the generated PNGs.
