Support TLS/SSL for the Postgres wire protocol plugin

[LepsyMikolaj3301]

Hi ArcadeDB team,

I noticed in #4472 that Postgres wire protocol doesn't support SSL/TLS yet, while HTTP/REST already does.
Standard Postgres-wire clients (the official JDBC driver, psql, BI tools, and notably Apache Spark via spark.read.jdbc/spark.write.jdbc) all expect to negotiate TLS through the protocol's own handshake. Many of these clients/environments default to sslmode=require.
Right now the only way around that is putting a tunnel (SSH/VPN) in front of the port, which might be a bit of a pain to maintain, especially for something like a Spark cluster.
Is this something that's already planned, or being considered for an upcoming release? If not yet, would love to hear whether it's something the team would consider adding.
