fix(types): fix Paper class method parameter typings in joint.d.ts

[Geliogabalus]

Summary

• Fix FORM_CONTROLS_TAG_NAMES → FORM_CONTROL_TAG_NAMES (typo, matches implementation)
• Fix insertLayerView second param from before?: Paper.LayerRef to beforeLayerView: LayerView | null (matches actual resolved type passed by callers)
• Fix requestLayerViewRemoval — add missing opt? parameter
• Fix checkMountedViews / checkUnmountedViews — widen first param from ViewportCallback to ViewportCallback | CellVisibilityCallback | null
• Fix sortViews / sortViewsExact → sortLayerViews / sortLayerViewsExact (correct method names)
• Fix drawBackgroundImage — img now accepts null, opt is optional
• Fix updateBackgroundColor — color is optional (called with potentially-undefined values)
• Fix createViewForModel — add missing cid?: string parameter
• Fix cloneOptions — return type Paper.Options → void (no return statement in implementation)
• Fix onGraphLayerCollectionSort — param type GraphLayer[] → mvc.Collection<GraphLayer> with correct name layerCollection
• Fix onGraphBatchStop (Paper class) — add missing data?: { batchName: string } parameter
• Fix renderView — add missing opt? parameter

Test plan

• Run yarn test-ts to validate TypeScript definition correctness
