Max Peintner 9dc127ddb5 fix(login): Prevent double execution of IDP callback token and improve architecture (#10948)
Closes #10828 

# Which Problems Are Solved

The IDP callback flow was calling retrieveIDPIntent() twice, causing
single-use token failures with error: "Intent Token is invalid". This
occurred due to Next.js 15's dynamicIO feature triggering double renders

# How the Problems Are Solved

Completely refactored the IDP callback architecture to ensure single-use
tokens are consumed exactly once:

- Centralized Business Logic: Moved all IDP callback logic into a single
server action (processIDPCallback) that:
   - Consumes the token once
- Handles all 6 business scenarios (login, linking, auto-linking,
auto-creation, manual registration, account not found)
   - Integrates session creation in the same action
- Returns `{ redirect?: string; error?: string }` for client-side
navigation
- Client Component Invocation: Created `IdpProcessHandler` client
component that:
- Calls the server action from browser context (enables cookie
modification)
   - Prevents double execution with useRef
   - Handles loading states and error display
- Clean Architecture:
   - Removed 403-line success page with complex logic
   - Removed component files from `/components/idps/pages/` folder
   - Moved all UI directly into server pages
   - Created dedicated result pages with minimal params

# Additional Changes

- Added translations to all 8 supported languages
