Replace the five 2FA stub methods in Settings with real implementations
that delegate to the TwoFactorAuthenticatable trait from php-tenant.
The 2FA tab now auto-enables when the User model uses the trait, and
handles the full lifecycle: enable, verify, confirm, view/regenerate
recovery codes, and disable.
Remove the orphaned BoostPurchase Livewire component and its blade
template. The /boosts route already redirects to the account usage
page's boosts tab, making this component dead code.
Update language strings: remove the old "upgrading" stub message and
add proper 2FA success/error messages.
