fix: permission checks on session API

# Which Problems Are Solved

The session API allowed any authenticated user to update sessions by their ID without any further check.
This was unintentionally introduced with version 2.53.0 when the requirement of providing the latest session token on every session update was removed and no other permission check (e.g. session.write) was ensured.

# How the Problems Are Solved

- Granted `session.write` to `IAM_OWNER` and `IAM_LOGIN_CLIENT` in the defaults.yaml
- Granted `session.read` to `IAM_ORG_MANAGER`, `IAM_USER_MANAGER` and `ORG_OWNER` in the defaults.yaml
- Pass the session token to the UpdateSession command.
- Check for `session.write` permission on session creation and update.
  - Alternatively, the (latest) sessionToken can be used to update the session.
- Setting an auth request to failed on the OIDC Service `CreateCallback` endpoint now ensures it's either the same user as used to create the auth request (for backwards compatibilty) or requires `session.link` permission.
- Setting an device auth request to failed on the OIDC Service `AuthorizeOrDenyDeviceAuthorization` endpoint now requires `session.link` permission.
- Setting an auth request to failed on the SAML Service `CreateResponse` endpoint now requires `session.link` permission.
