fix: cocoa SDK init after hot-restart

[vaind]

📜 Description

Fixes #2412 by letting the CocoaSDK know it should start the session when we init it.

💡 Motivation and Context

See issue description in getsentry/sentry-cocoa#4575

💚 How did you test it?

📝 Checklist

• I reviewed submitted code
• I added tests to verify changes
• No new PII added or SDK only sends newly added PII if sendDefaultPii is enabled
• I updated the docs if needed
• All tests passing
• No breaking changes

🚨 Detected changes in high risk code 🚨

High-risk code has higher potential to break the SDK and may be hard to test. To prevent severe bugs, apply the rollout process for releasing such changes and be extra careful when changing and reviewing these files:

• flutter/ios/Classes/SentryFlutterPluginApple.swift
