fix(pack): route /tutorial/pack_open through the normal path

Browse Source 
The tutorial pack-open alias hardcoded parent_gacha_id=99047 (the May 2026
throwback pair), so once the June rotation replaced it with 99032 the
tutorial's final pack-open 400ed. Fix the identity gate by removing it:
/tutorial/pack_open is now a plain alias for /pack/open with a single
epilogue that advances TutorialState to 100 and emits tutorial_step=100.

The tutorial gift's TICKET_MULTI item naturally scopes what the alias
can open — the normal path's ticket-debit branch already consumes it,
so no separate tutorial-path bypass is needed. Also drop the July-1
expiry on packs 80032/99032 so the current throwback pair stays visible.
