fix(levels): ScenePath must be a string, not a PackedScene

slice 7 regression. level_village_2..5.tscn each reference their own
LevelResource for the death screen label, so pointing the resource back
at the scene forms a cycle Godot cannot resolve - "Parse Error: Busy"
and the level fails to load entirely.

ScenePath was a string for exactly this reason. Reverted, and the rot it
allowed (forest_1 aimed at a nonexistent scene) is now caught by
LevelCatalogue.Validate checking every path resolves, plus a repo-level
structural check - fixed by validation rather than by typing.

project.godot: restores the C# feature flag and dialogue_manager
uses_dotnet, which `godot --headless --import` strips on every run.
