🟢 Approval recommended

The changes are a straightforward internal rename/refactor with verified reference updates and no remaining usages of the removed module.

Pull request overview

This PR updates the internal EventsStrategy implementation to a better-typed TypeScript module and adjusts entry points/imports to reference the new module, removing the legacy m_events_strategy file.

Changes:

• Replaced __internal/core/m_events_strategy.ts with a new __internal/core/events_strategy.ts that adds explicit TS types/interfaces.
• Updated the deprecated public entry js/core/events_strategy.js to re-export from the new internal module.
• Updated Knockout validation integration to import EventsStrategy from the new @ts/core/events_strategy module.

🔵 Needs a closer look

The new TypeScript implementation introduces typing/unused-parameter issues that are likely to be flagged by lint/TS rules and should be corrected before merging.

packages/devextreme/js/__internal/core/events_strategy.ts:5

• Avoid using the Function type for event handlers; it disables parameter/return type checking and is inconsistent with other callback typing in the codebase (e.g. document_size_callbacks.ts uses a concrete function signature). Use an explicit callable signature instead.
  packages/devextreme/js/__internal/core/events_strategy.ts:100
• The eventName parameter in this callback is unused; this is likely to be flagged by TS/ESLint unused-parameter rules. Use _ (or prefix with _) to mark it intentionally unused.
