react-meteor-data: support TypeScript 7

[italojs]

Summary

Adds typescript@7.0.2 to the explicit supported constraint used by react-meteor-data and releases the corresponding package version as 4.1.0-beta.1.

Why

The constraint inferred through api.versionsFrom only supports TypeScript through 5.4.3. Apps that use react-meteor-data therefore cannot select TypeScript 7.

This PR makes the supported TypeScript versions explicit and adds TypeScript 7 support. It does not add a TypeScript 6-specific constraint. It supports meteor/meteor#14319.

Replaces #490 and #496.

Validation

• Reproduced the dependency-solver conflict with typescript@7.0.2 before the change.
• Confirmed a temporary Meteor app can select typescript@7.0.2 with the updated local package.
• Ran meteor npm run test:ci in tests/react-meteor-data-harness (56 passed).

react-meteor-data@4.1.0-beta.1 has been published.
