Posthog analytics + change of monetization strategy

It's hard to get traffic for a paid app. The response to it - make the app free and try subscriptions. That means the new release with:

1. Posthog analytics (on consent only)

2. New subscription-based monetization

3. New onboarding + paywalls

Aside that I also worked on features:

• Now you can attach photos to journals

• Learn screen redesigned to simplify the learning

• ML crisis detector is now opt-in Beta

Also, built an automated screenshot pipeline to save some time.
