fix: correct FOUNDERS_EDITION handling and polling behavior

- Map FOUNDERS_EDITION to 'standard' tier for current plan display
- Change polling to only start on window focus (when user returns from checkout)
- Clean up event listeners properly in onBeforeUnmount
- Improves UX by not polling immediately when dialog opens
