IS-11570 Add browser back/forward navigation to the HAAPI stepper

[aleixsuau]

Jira: https://curity.atlassian.net/browse/IS-11570

Adds useHaapiStepperHistoryNavigation and mounts <HaapiStepperHistoryNavigation /> in the app, wiring the browser Back/Forward buttons to the HAAPI stepper:

• Records every reached step as a browser-history entry, mirrored in an in-memory model.
• Back/Forward re-opens the nearest reproducible step (GET link / GET form) in the direction of travel, skipping non-reproducible ones (POST forms, client operations).
• Truncates abandoned forward branches, mirroring native pushState behaviour.

Testing

Run a HAAPI flow and use the browser Back/Forward buttons: reproducible steps (GET links / GET forms) are revisited, non-reproducible ones (POST forms, client operations) are skipped.

Unit tests: npx vitest run src/shared/feature/history.
