EDU-17940: rename Trade Policy to Sales Channel in documentation

[PedroAntunesCosta]

• Renamed "Trade Policy" references to "Sales Channel" in the documentation text to align with the platform-wide terminology update.
• Replaced GitHub-specific emoji shortcodes (:information_source:, :warning:) with actual Unicode emojis for consistent rendering across all platforms.
• Added a warning note clarifying that code references (e.g., challenge.trade-policy-condition) still use the old naming for backward compatibility.

Why

The platform is transitioning from the "Trade Policy" terminology to "Sales Channel". This update ensures the documentation reflects the correct naming while preserving backward-compatible code identifiers.
