Restricts markdown feedback actions to custom scheme

Updates menu conditions so feedback actions for markdown previews only appear when the editor uses the dedicated custom resource scheme, preventing display in standard markdown previews. Adjusts menu order for better navigation grouping and consistency.

Aligns command visibility with intended context to avoid confusion and clutter in the editor UI.
