Added "Tileset > Edit Tileset Image Parameters..." action

This makes the functionality easier to discover. Previously editing the tileset image parameters was only possible by clicking the value of the Image property in the Properties view, and then the appearing "Edit" button.

⚡ Recommended focus areas for review Update Consistency The new action for editing tileset parameters is integrated using updateActions instead of the former updateAddRemoveActions. Please verify that all UI state changes (such as enabling/disabling actions) are consistently applied in all contexts where the state update is needed. updateActions(); } Default Initialization The TilesetParameters struct now includes a default constructor and default initializers for tileSpacing and margin. Confirm that these default values are appropriate across all usages and do not unintentionally affect behavior when comparing parameter changes. TilesetParameters() = default; explicit TilesetParameters(const Tileset &tileset); bool operator != (const TilesetParameters &other) const; QUrl imageSource; QColor transparentColor; QSize tileSize; int tileSpacing = 0; int margin = 0; };

Oh well, the agent failed to understand a line was added to a function rather than a "duplicate" being added. For a moment I thought it might have caught the duplication between TilesetEditor::editTilesetParameters and TilesetParametersEdit::buttonClicked, but no, I think the latter was likely not in the context.
