Display connection info and SSL status on startup

[NikolayS]

Summary

Enhanced the startup output to display connection details and SSL status information, matching the output format of psql.

Key Changes

• Added connection information display during server startup using connection::connection_info() function
• Added a blank line after the help text to improve output readability and formatting consistency

Implementation Details

The connection details are now printed immediately after the PostgreSQL server version information, providing users with visibility into their connection parameters and SSL status at startup. This aligns the application's output with standard psql behavior, making the startup experience more familiar to PostgreSQL users.

POTENTIAL ISSUES (1)

LOW src/main.rs:~882 — Resolved IP address exposed in startup output (confidence: 4/10)

When connecting via hostname (TCP), connection_info() includes the resolved IP address: on host "myhost" (address "10.1.2.3") at port "5432". This matches psql behaviour but may surprise users who expect internal IP addresses to stay invisible (e.g., in shared environments where terminal output is logged). No fix needed given it matches psql — just worth confirming it's intentional.

Notes:

• connection_info() already has 5 unit tests in src/connection.rs covering TCP, TCP+TLS, socket, resolved-addr, and no-TLS paths — no new tests needed.
• Change is correctly gated behind !cli.quiet && is_interactive — no output in scripted or quiet mode.
• No credentials are included in the output (password is not part of ConnParams output).

Superseded by #817, which includes all changes from this PR (connection info display, config.toml hint, blank line) plus the CodeQL security fix that required using ConnDisplayInfo instead of passing the full ConnParams to display functions.
