fix(auth): correct the Kratos recovery -> password-reset handoff

The recovery code was submitted to a freshly-initialised recovery
flow, but Kratos binds the emailed code to the original flow, so
verification could never succeed. The settings step then ran with no
privileged session, so the password change would be rejected too.

- forgotPassword remembers its recovery flow action; verifyResetCode
  submits the code back to that SAME flow.
- verifyResetCode parses Kratos continue_with for the privileged
  session token + the settings flow id; resetPassword submits the new
  password to that settings flow authenticated with X-Session-Token.
- KratosFlow / KratosContinueWith models extended (continue_with,
  ory_session_token).

Resolves the TODO(kratos) in AuthApi.resetPassword.
