feat(loyalty): cross-persona page alignment with shared components

Align loyalty pages across admin, merchant, and store personas so each
sees the same page set scoped to their access level. Admin acts as a
superset of merchant with "on behalf" capabilities.

New pages:
- Store: Staff PINs management (CRUD)
- Merchant: Cards, Card Detail, Transactions, Staff PINs (CRUD), Settings (read-only)
- Admin: Merchant Cards, Card Detail, Transactions, PINs (read-only)

Architecture:
- 4 shared Jinja2 partials (cards-list, card-detail, transactions, pins)
- 4 shared JS factory modules parameterized by apiPrefix/scope
- Persona templates are thin wrappers including shared partials
- PinDetailResponse schema for cross-store PIN listings

API: 17 new endpoints (11 merchant, 6 admin on-behalf)
Tests: 38 new integration tests, arch-check green
i18n: ~130 new keys across en/fr/de/lb
Docs: pages-and-navigation.md with full page matrix
