Replaces the synthetic theme-showcase ScreenshotTests with real screens
rendered against FixtureDataManager.empty() / .populated() via
LocalDataManager. GallerySurfaces.kt manifest declares 40 screens.
Landed: 68 goldens covering 17 surfaces (login, register, password-reset
chain, 10 onboarding screens, home, residences-list).
Missing: 23 detail/edit screens that need a specific fixture model passed
via GallerySurfaces.kt — tracked as follow-up in docs/parity-gallery.md.
Non-blocking: these render silently as blank and don't fail the suite.
Android total: 2.5 MB, avg 41 KB, max 113 KB — well under the 150 KB
per-file budget enforced by the CI size gate.
