Post Phase 8 - Fixes 1

Delivered:

Super Administrator — env-var provisioned, no StaffProfile at all (structural exclusion from Team/barber-picker/appointments/staff-totals, not a filter). hasPermission short-circuit + new getActingBusinessContext() helper retrofitted across 16 owner pages so it can actually manage the business.
Media Manager — one upload/library/external-URL modal + field picker, backing every image field app-wide. Local-disk storage + Docker volume, SVG rejected, size-capped.
Welcome backgrounds — desktop/mobile images with CSS breakpoint swap.
Business Branding settings — logo/cover/welcome/favicon/icon/colours all editable post-install; cover image finally rendered (was dead config).
Service descriptions — now surfaced on Home and in the booking flow.
Loyalty card — live preview, ColorPicker/MediaPicker/IconPicker, flip removed for a static premium-styled card, Loyalty added to bottom nav. Fixed a real pre-existing bug where the card's configured colour/image/icon were stored but never actually rendered.
Home Screen Redesign — hero gallery + sticky Services/Portfolio/Reviews/Details tabs, backed by a new unified gallery model/service (no hero/portfolio duplication). Details tab surfaces social links and a map that were never shown before.
Google Reviews — real sync pipeline (24h cron, CRON_SECRET-gated, mirrors the existing notification cron exactly), DB-only customer reads, owner hide/unhide + policy management page.
Architecture cleanup — SettingsPageShell extracted from 6 duplicated page wrappers; fixed a second pre-existing bug where branding image fields could never actually be cleared once set.
Verification: 418 tests passing (236 unit + 182 integration, all against a real MySQL database), full typecheck/lint clean across src, and a real Docker build+run cycle — which caught and fixed a genuine bug (scripts/ wasn't copied into the production image, so Super Admin sync would have crashed on every real deployment).
