feat: centralize PostHog analytics with proper error handling

- Create lib/analytics.ts with centralized tracking functions
- Use arrow functions and camelCase naming per code standards
- Add error handling to prevent analytics failures from crashing app
- Update auth forms and provider workflows to use new analytics lib
- Export TypeScript interfaces for type-safe analytics payloads

Addresses PR review comments:
- Convert to arrow functions (requested by @paabloLC)
- Use camelCase for event and property names
- Centralize analytics logic for better maintainability
