fix(SingleThreadedFragmentsModel)!: apply common fragments model interface

[ShaMan123]

Description

closes #216

• drop redundant async directives
• BREAKING: rename SingleThreadedFragmentsModel#getItemsWithGeometry to getItemsWithGeometry for compat with FragmentsModel
• exposed getItemsVolume

Additional context

Misalignments — methods present in one class but absent (or internal) in the other

• In FragmentsModel only (missing from SingleThreadedFragmentsModel):
• • getGuids() — VirtualFragmentsModel exposes this but SingleThreaded does not.
• • getItemsWithGeometryCategories() — same situation.
• • getItemsIdsWithGeometry() — FragmentsModel only.
• • getCoordinationMatrix() — FragmentsModel only.
• • getMergedBox() / getBoxes() — FragmentsModel only.
• • getAlignments() / getHorizontalAlignments() / getVerticalAlignments() / getAlignmentStyles() — FragmentsModel only.
• • getGrids() / getGridMaterial() / setGridMaterial() / getGridLabelMaterial() / setGridLabelMaterial() — FragmentsModel only.
• • useCamera() / setLodMode() — FragmentsModel only.
• • raycast() / raycastAll() / raycastWithSnapping() / rectangleRaycast() — FragmentsModel only.
• • setVisible() / toggleVisible() / resetVisible() / getVisible() / getItemsByVisibility() — FragmentsModel only.
• • highlight() / setColor() / resetColor() / setOpacity() / resetOpacity() — FragmentsModel only.
• • getHighlight() / resetHighlight() / getHighlightItemIds() — FragmentsModel only.
• • getItemsMaterialDefinition() — FragmentsModel only.
• • getAttributesUniqueValues() — FragmentsModel only.
• • getEditedElements() — FragmentsModel only.
• • getItemsVolume() — FragmentsModel only.
• • getAttributeNames() / getAttributeValues() / getAttributeTypes() / getRelationNames() — FragmentsModel only.
• • getGeometries() — FragmentsModel only.
• • getItem() — FragmentsModel only.
• In SingleThreadedFragmentsModel only (absent or internal in FragmentsModel):
• • edit() — public in SingleThreaded; FragmentsModel exposes _edit() (internal) and routes edits through the Editor class.
• • reset() / save() — same; _reset() / _save() are internal in FragmentsModel.
• • undo() / redo() — SingleThreaded only; no equivalent in FragmentsModel.
• • getRequests() / setRequests() / selectRequest() — SingleThreaded only; _getRequests() etc. are internal in FragmentsModel.

breaking!

[ShaMan123]

fixed signature, non breaking

Ready for review
Regarding file/interface naming please suggest to desired pattern so I can align with standards.

Should IModelSerializer methods return Uint8Array only?
