SC-44615

[sonar-review-alpha]

Summary

Updates react-intl dependency from v6 to v10 (4 major versions). This is a significant version bump that may introduce breaking changes. The diff shows only package.json and yarn.lock modifications—no application code changes are visible in this PR, suggesting either the codebase is already compatible with v10's API or compatibility work was done previously.

What reviewers should know

Start by checking:

• The repository uses react-intl extensively (FormattedMessage, useIntl hooks, etc. in ~30+ components)
• Since no source code changes are shown, verify that v10 compatibility is already baked in or that migration was completed on another branch

Key review concerns:

• React-intl v6→v10 spans 4 major versions with potential breaking changes; familiarize yourself with the migration guide if unfamiliar
• Confirm this passes all CI checks (tests, linting, builds) to ensure the bump doesn't break the application
• Check the yarn.lock changes match expected dependency tree adjustments

For context:

• The commit message references SC-44615; check if there are related issues or acceptance criteria
• The package.json also shows react@^19.0.0, so this is a modern React codebase already using current versions

LGTM! ✅

Clean, minimal change — only the peer dependency version range and lock file entry are updated. No application code changes are needed, indicating the codebase is already compatible with react-intl v10.
