Introduce server-side control-logic flow graphs (cron/alarm triggers, Lua blocks) with CRUD endpoints, panel-logic lifecycle triggers and user-interaction dialog nodes, and a synthetic node-graph editor. Add an optional logic-editor allowlist (server.logic_editors) gating who may add/edit panel logic and control logic, surfaced via /api/v1/me and enforced in the API; hide logic affordances in the UI accordingly. Update README, example config, and functional/technical specs to cover all current features (plot panels, panel/control logic, local variables, access control) and refresh the in-app manual and contextual help.
