fix(active-identity): complete component migration to new Active Identity system

Fixes gift recording functionality by migrating remaining components from
legacy settings.activeDid to new $getActiveDid() method. Migration 004
dropped settings.activeDid column before all components were updated,
causing validation failures in GiftedDialog, OfferDialog, and
OnboardingDialog. Added comprehensive logging to $getActiveDid() method
and HomeView initialization for debugging. Test "Check User 0 can register
a random person" now passes consistently.

- GiftedDialog, OfferDialog, OnboardingDialog use new Active Identity system
- Enhanced logging in PlatformServiceMixin.$getActiveDid() method
- Added debugging logs to HomeView component lifecycle
- Fixed Playwright test navigation and element selectors
