feat: multi-factor attachment support for Advanced dbs (W-21632630)

[sbosio]

Summary

Here we introduce updates to support Multi-Factor Attachments on NGPG commands.

The main changes revolve around:

• Introduction of a new library function: parseAttachmentFactors that parses attachment namespace strings into role / pool / proxy (pipe-separated, backward-compatible with single-factor attachments). Includes unit tests.
• data:pg:attachments:create now prompts for non-provided flag option values. For non-interactive experience, all pool, credential and as flags option values need to be specified. Missing values will be interactively prompted.
• Other data:pg topic commands where updated to stop relying on exact namespace === "role:…" (and similar) comparisons and use parsed factors for credentials topic (list, rotate, destroy), info and attachments commands. Other related helpers/types were updated for compatibility.
• data:pg:psql command drops the credential flag so connection selection fits multi-factor attachments.
• Tests & fixtures were updated adding new tests for multi-factor attachments and the new interactive prompting behavior.
