desktop M10.3: frontend data-source adapter seam (repo interface + rest.ts)

Extract a typed repository interface (adapters/repo.ts) from the scattered
store/view -> api.* calls, backed by adapters/rest.ts (verbatim HTTP mapping)
and selected through adapters/index.ts. Every store and the notes-facing views
now depend on `repo`, never the HTTP client directly -- the seam the offline
local source (M10.5, over Tauri invoke) plugs into next.

Behavior-preserving for web: rest.ts maps each semantic method to the exact
endpoint the code called before; query-string and multipart building moved out
of the stores/views into rest.ts (the one place that knows the URL shape).
Client-side logic (reconcile/sort/optimistic reorder/toasts) stays in the
stores. GraphView + admin SettingsView keep direct api calls -- out of the
offline-core scope (M10.5 is board/editor/capture/search/filter/labels/
checklists/reminders).

Task 1992.
