### SUMMARY
Migrates the dashboard feature's state management off Redux to **Zustand**
(client/UI
state) and **TanStack Query** (server state), as part of the frontend
state-management
modernization (SIP-207).
**Client/UI state → Zustand** (5 dashboard reducers replaced by domain
stores):
- `dashboardState`, `dashboardInfo`, `dashboardLayout` (undo/redo via
`zundo`),
`nativeFilters`, `dashboardSlices`
- Each store follows a domain-layer convention: `hooks.ts` for reactive
reads and
`actions.ts` for imperative writes, with the raw store never exported.
**Server state → TanStack Query** (`src/dashboard/queries/`):
- Reads: dashboard detail, slices, themes, CSS templates, favorite status,
dataset
metadata, related options.
- Mutations: save, properties, publish, favorite, filter-config,
chart-customization,
chart-configuration, with query-key invalidation and discard-snapshot
rebaselining.
**Intentionally out of scope (still Redux):** charts, datasources, and
`dashboardFilters`. These keep their existing Redux bridges by design.
The change is **behavior-preserving**: no user-facing UI or UX change. It is
a state
layer refactor that keeps all existing dashboard functionality intact.
### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
N/A. No visual change. The dashboard renders and behaves identically; this
PR only
changes how state is stored and fetched.
### TESTING INSTRUCTIONS
1. Open several dashboards (with tabs, native filters, cross-filtering).
Confirm charts
render.
2. Edit mode: make layout edits (add/move/resize/delete components, edit
markdown,
add/rename/delete tabs). Confirm Undo/Redo and in-place Discard all work.
3. Change properties (name, theme, color scheme, CSS), Save, reload, confirm
persistence.
4. Toggle favorite and publish; confirm both persist across reload.
5. Apply/clear native filters and cross-filters; set/clear an auto-refresh
interval.
