fix: recreate offer for issuance and presentation sessions

[cre8]

Summary

Fixes #502 — the "Recreate Offer" feature was broken for issuance sessions and missing for presentation sessions.

Changes

Issuance recreate offer fix

• Flow type mapping: OfferRequestDto stores 2 flow types (authorization_code | pre_authorized_code) but the form UI uses 3 values. prefillFromOffer() now correctly maps authorization_code → authorization_code_external or authorization_code_iae based on the credential config's IAE actions and authorization_server field.
• Race conditions: Refactored ngOnInit() to async with Promise.all() — all configs are loaded before prefilling. Value change subscriptions are set up after prefill to avoid interference.
• Stepper navigation: When recreating, the stepper now jumps directly to the last step so the user can review and submit immediately.

Presentation recreate request (new)

• canRecreateOffer() now returns true for presentation sessions that have a requestId.
• recreateOffer() navigates to /offer/presentation with the requestId in navigation state.
• PresentationRequestComponent picks up the prefill data and patches the form.
• Button text dynamically shows "Recreate Offer" or "Recreate Request" depending on session type.
