Max Peintner 00beaf6ddc fix(login): provide a postError redirect url for idp flows (#10883) ...

# Which Problems Are Solved

Improves the user experience when IDP authentication succeeds but user
creation/linking fails by introducing a `postErrorRedirectUrl` parameter
and dedicated error pages instead of generic error screens.

# How the Problems Are Solved

## New Pages
- **`/idp/[provider]/account-not-found`**: Displayed when no user
account exists and creation/linking is not allowed
- **`/idp/[provider]/registration-failed`**: Displayed when user
registration fails due to organization resolution issues

## Flow Improvements
- Added `postErrorRedirectUrl` parameter to track where the IDP flow was
initiated
- Each entry point (loginname, register, idp, authenticator/set)
specifies its own redirect URL
- Users are now redirected to appropriate error pages with clear
messaging instead of generic error screens
- All context (`requestId`, `organization`, `postErrorRedirectUrl`) is
preserved throughout the flow

## Updated Components
- `SignInWithIdp`: Now accepts and passes `postErrorRedirectUrl`
parameter
- `redirectToIdp` server action: Extracts and forwards
`postErrorRedirectUrl` through the IDP flow
- IDP success page: Routes to appropriate error pages based on failure
reason

## i18n
Added new translation keys:
- `idp.accountNotFound.*` - For missing account scenarios
- `idp.registrationFailed.*` - For organization resolution failures
