#10546 - Refactor: Explicit/implicit Any type clean up from packages\ketcher-react\src\script\editor\tool\bond.ts file

[Copilot]

Removes all explicit and implicit any types from packages/ketcher-react/src/script/editor/tool/bond.ts, replacing them with precise TypeScript types.

How the feature works? / How did you fix the issue?

New types file bond.types.ts:

• BondItemRef — { map: string; id: number } for item references
• BondToolDragContext — typed drag state (replaces dragCtx: any)
• BondActionParams — parameters for applyBondAction

bond.ts changes:

• bondProps: any → Partial<BondAttributes>
• dragCtx: any → dragCtx?: BondToolDragContext
• All event handlers typed as PointerEvent; all private method parameters fully typed
• Imported BondAttributes, AtomAttributes, Render, Pool, SGroup, FunctionalGroup, Bond from ketcher-core
• Replaced multiple ! non-null assertions with proper guards and narrowing:
  • resolveAtomDragTarget now accepts item: BondItemRef directly (caller narrows via dragCtx.item?.map === 'atoms' guard)
  • restoreBondWhenHoveringOnCanvas split into sequential guards so TypeScript narrows existedBond, item, and action without assertions
  • resolveEndAtomPosition has typeof beginAtom !== 'number' type guard and null check for atom before property access

Also fixed: pre-existing unused import (takeElementScreenshot) in ketcher-autotests/tests/specs/Bugs/ketcher-2.28.0-bugs.spec.ts that was blocking the pre-push hook.
