feat(settings): add preview_settings for per-extension preview management

okatu-loli · okatu-loli · commit 1db7a942bf11 · 2026-05-28T20:23:01.000+08:00
Adds a new admin setting `preview_settings` (text/JSON, default `{}`) in the PREVIEW group. It is the per-extension override layer (order + disabled IDs) consumed by the new admin UI in alist-web. The setting is orthogonal to iframe_previews / external_previews — no migration code, no shadow writes. Backup/restore works across version boundaries because old clients simply ignore the unknown key. Companion frontend PR: AlistGo/alist-web#306 Closes #9542
