fix(scopes): apply withScope data to events in globalHubMode

[markushi]

📜 Description

Sentry.withScope forks the current scope and makes it current, but Sentry.getCurrentScopes short-circuited to rootScopes when globalHubMode was enabled, so the fork was never read back. Everything set inside the callback was silently dropped.

Honour scopes that were explicitly made current, as long as they descend from the current rootScopes. Implicit forking stays suppressed. pushScope and popScope remain no-ops, since they are unbalanced.

💡 Motivation and Context

globalHubMode is on by default on Android, so this affected all Android users since 8.0.0.

• resolves: HTTP request payload and response body not captured in error events #5339
• resolves: JAVA-489

💚 How did you test it?

Unit tests in SentryTest.kt, run for globalHubMode both true and false. Verified they fail without the fix.

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
• Public API changes reviewed by another Mobile SDK team member or implemented according to the develop docs spec.

🔮 Next steps

Hybrid SDKs relying on withScope being a no-op under globalHubMode should be made aware.
