• AnalyticsService only tracks token usage events

After this PR:

• AnalyticsService tracks app launch events on startup, reporting app version and OS platform

Why we need it and why it was done in this way

The following tradeoffs were made:

• Uses the generic track() method instead of trackAppLaunch() to avoid type definition inconsistencies with the SDK

The following alternatives were considered:

• N/A

Breaking changes

None

Special notes for your reviewer

• The trackAppLaunch() is called at the end of init(), ensuring analytics client is initialized first
• Respects data collection settings - no tracking if disabled
