Remove the extensible theme catalog (config/themes.php + ThemeConfigGateway)
in favor of a two-entry const on SettingsAppGateway. appThemes() now returns
the list directly — no container lookup, no file include. Drop the
dark-green theme assets, narrow [data-theme^="dark"] selectors to
[data-theme="dark"], and tighten isDarkTheme() to an exact match. Ship an
idempotent migration that corrects any leftover 'dark-green' rows on users
and tenants to safe defaults (light / NULL).
Tenant scoping (default_theme, allow_user_theme) and per-user override stay
intact; only the catalog extensibility and the third theme are removed.

Removes the global app_theme, app_theme_user and app_primary_color settings
from the admin/settings area and the underlying service/cache/API/i18n/docs
layers. The tenant columns (tenants.primary_color, default_theme,
allow_user_theme) become the single source of truth for appearance.
Branding helpers are tenant-only and fall back to a hardcoded 'light' theme
with no brand color when no tenant context is available (login, error,
pre-session pages). The APP_THEME env var is removed.
Scope:
- UI: Appearance tab gone from /admin/settings; tenant edit form drops the
global-fallback color preview.
- Service: SettingsAppGateway no longer exposes setting-backed accessors
for theme/user-theme/primary-color. Theme catalog utilities (listThemes,
isAllowedTheme, normalizeTheme, resolveDefaultTheme) stay and are used
across Tenant / Auth / User flows; resolveDefaultTheme now hardcodes
'light' with a catalog fallback (no global/env lookup).
- AdminSettingsService: buildPageData, sanitization, audit snapshot, apply
step and cache payload are all stripped of the three keys. Dead helper
applyAppPrimaryColor + normalizePrimaryColor removed.
- Cache: SettingCacheService HOT_PATH_KEYS drops the three keys.
- API: /settings (GET/PUT) and /settings/public (GET) no longer expose
appearance fields; OpenAPI schemas pruned accordingly.
- Audit redaction list shortened.
- DB: db/init/init.sql seed rows removed. No migration for existing
installs — legacy rows stay inert.
- i18n + docs: setting.app_theme, setting.app_theme_user,
setting.app_primary_color removed from de+en locales; reference and
explanation docs updated.
- Tests: covering tests for the removed methods pruned; ThemeResolutionTest
rewritten for tenant-only semantics. One unrelated PHP-CS-Fixer issue in
UserRegistrar.php cleaned up to keep QG-006 green.
Workflow: .agents/runs/SETTINGS-APPEARANCE-TENANT-ONLY/ (gitignored).
Gates: QG-001..003, QG-006, QG-008 all pass (1985 tests, 28764 assertions).
Reviews: code, security, acceptance all pass.
