slideshowSettings used settingsService.getSetting, which queries db('settings')
- a table that does not exist in this app (globals live in app_settings). Every
GET /gallery/:slug/show/:token/session and /state therefore threw and returned
500 INTERNAL_ERROR once a valid token resolved. Switch to getAppSetting
(utils/appSettings), which reads app_settings where the slideshow_watermark_*
and branding_* values are actually written.
