feat: phase 1 MVP — sections, services, drag-drop, renderers

Backend: migration 0002 (sections/items/urls/settings), CRUD +
fractional reorder, icon upload, settings, export/import, cached
status pings. Handler tests cover reorder, URL scheme validation,
settings round-trip.

Frontend: shared board store over the generated client, dnd-kit
layer (same-section, cross-section, section reorder persisted),
URL chooser popover, add/edit service dialog, settings dialog,
Bento + Cards renderers behind the shared seam, dark/light theme.

 The product's spine: sections, services, drag-drop, multi-URL.
 
-- [ ] Schema: `sections`, `items`, `urls`, `settings` (fractional `position REAL` ordering)
-- [ ] REST API: CRUD for sections/items/urls, `reorder` endpoints, icon upload, `settings`, `export`/`import` JSON
-- [ ] Renderer contract: shared board store + `BoardView`/`SectionView`/`ItemView`/`WidgetView` seam, dnd + popover as shared primitives
-- [ ] **Bento** renderer (default): mixed-size grid, hairline section headers, tiles with status chips
-- [ ] **Cards** renderer: uniform compact grid — second renderer proves the seam while code is small
-- [ ] dnd-kit: reorder items in a section, move items between sections, reorder sections; persist on drop
-- [ ] Collapse/expand sections (persisted)
-- [ ] `UrlPopover`: 1 URL → direct open, 2+ → chooser (`local`/`external`/custom tags)
-- [ ] `AddServiceDialog` / `EditServiceDialog` (name, URLs+labels, icon URL or file upload)
-- [ ] Icon handling: upload to `data/icons/`, remote URL passthrough, letter-tile fallback
-- [ ] Dark/light toggle (persisted), renderer picker in settings, responsive to ~360px
-- [ ] Status ping: server-side HEAD request per service URL, cached ~60s → `up`/`down` chip
