Update settings (vibe-kanban) (#148)

* Added support for `telemetry_acknowledged` in the Privacy section. It follows the same pattern as the disclaimer and onboarding acknowledgments with:

- Status display showing whether it's been acknowledged
- Reset button to clear the acknowledgment (disabled when not acknowledged)
- Explanatory text about what happens when reset
- Visual separation from the analytics toggle with a border

The field will now be properly managed in the Settings UI and can be reset if needed, requiring re-acknowledgment on the next app start.

* Moved the telemetry acknowledgment from the Privacy section to the Safety & Disclaimers section. It's now grouped with the other acknowledgments (disclaimer and onboarding) which makes more logical sense since they all follow the same pattern of managing user acknowledgments that can be reset to show notices again on app startup.

* Updated all three disclaimer texts to remove "on next app start" since users will need to acknowledge them immediately when reset, not on the next app startup.

* Changed the button text from "Complete Setup" to "Continue" in the OnboardingDialog component to better reflect that there are additional onboarding steps after this initial setup.

* Prettier formatting completed successfully! All files have been formatted, with only the Settings.tsx file having been updated (likely due to our recent changes).
