Subject: [PATCH] [FIX] linux: defer AnalyticsService init to avoid Firebase
 crash

Defer FirebaseAnalytics initialization to constructor to avoid crashes on
unsupported platforms (notably Linux). Replace class-level initialization
with nullable field and guarded calls.

Changes:
- remove class-level initialization of _analytics
- add private _init() invoked in constructor
- make _analytics nullable
- add null checks in logEvent() and setUserId()
- emit warning instead of throwing
- Linux builds no longer crash on startup
