Add hoover model.js as a central reactive store per subsystem, replacing per-component data fetching with a single source of truth. - Add hoover/model.js with modelRegister, modelFetch, and WS invalidation - Refactor websocket.js to route messages to model refresh (drop per-component subscribe/unsubscribe) - Simplify component.js by removing WS subscription management - Add refresh option to apiSubmit, deprecate refactorLoad and checkAbort - Rewrite all pages to use getModel() instead of inline data fetching - Bootstrap model registrations in app.js - Add GET /api/firewall/state endpoint - Fix restart-services.sh restart order and add service health verification - Update hoover.md docs with model layer architecture

/**

|
* Hoover — component.js
|
|
*
|
|
* Component wrapper: definePage, lifecycle hooks, state caching.
|
|
*
|
|
* definePage wraps a page definition into a renderer function compatible
|
|
* with hoover's render engine. Handles reactive state creation and
|
|
* lifecycle management. Data loading is handled by the model layer.
|
|
*
|
|
* Usage:
|
|
* export default definePage({
|
|
* init() { return { firewall: getModel('firewall') }; },
|
|
* async load(state) { ... }, // optional, for one-time setup
|
|
* render(state) { return [vnodes],
|
|
* });
