Version 2.28.0: Family sharing polish, clearer billing, and steadier iOS sync

🎉 What's New

Leave a family with confidence - Family members now see a confirmation step before leaving, making it clearer what shared access changes.
Family Sharing is easier to find - The website now includes a dedicated family page, updated docs, pricing details, and a blog post that explain how sharing works.
Names feel more natural - Onboarding and profile setup now use first names more consistently across Kualia.
FinanceKit import details are clearer - Apple Wallet import metadata and privacy information are now represented more consistently.

Fixed hard refreshes that could send you back to the budget page instead of keeping your current page.
Fixed billing management links so they open the right subscription account.
Improved iOS foreground recovery for rare cases where data stopped refreshing after reopening the app.
Fixed workspace drawer badges so they only appear where they are relevant.
Adjusted the budget activity popover so recent activity is easier to scan.
Made family invite acceptance more reliable even if internal notifications fail.
