* feat(ui): gateway-owned sidebar section order with hover-only drag grips
* fix(ui): repair sidebar section order CI gates
* fix(protocol): keep sectionOrder optional for older gateways
Native Swift clients ship separately from gateways, so new clients must decode older gateway responses that omit sectionOrder.
* fix(ui): reconcile gateway section ordering with main
* fix(state): allow lazy tables in v5 maintenance
* refactor(ui): retire prefs session section order in favor of gateway-owned order
Supersedes #113948 by deleting the unreleased ui.prefs.sessionSectionOrder key and its browser plumbing. Gateway SQLite sidebar_sections remains the single canonical store.
