## Summary
- remove the `real-estate` Pennant flag definition, request gating,
local auto-activation middleware, and frontend shared flag plumbing
- make real-estate account creation and onboarding availability the
default path for all users
- update feature and browser tests to cover default availability instead
of flag enable/disable behavior
## Testing
- vendor/bin/pint --dirty --format agent
- php artisan test --compact tests/Feature/RealEstateTest.php
- php artisan test --compact
tests/Feature/RealEstateAvailabilityTest.php
- php artisan test --compact tests/Browser/RealEstateAccountTest.php
- php artisan test --compact tests/Browser/OnboardingFlowTest.php
- php artisan test --compact --filter=\"can create a real estate account
linked to an existing loan\" tests/Browser/BankAccountsTest.php
## Notes
- `npm run build` completed the client build, but the Sentry sourcemap
upload step failed with an SSL/TLS error from the configured plugin
- deploy follow-up: run `php artisan pennant:purge real-estate` to
remove stale stored flag values
