feat(fase-2b): Realtime sync + offline queue + Modo Compra

Browse Source 
Fase 2b closes the critical-path product differentiator. Two sessions on the
same list see each other's changes in real time, mutations survive network
drops and sync when reconnected, and a dedicated full-screen shopping view
optimises the in-store experience.

2b.1 Realtime
- `$lib/stores/realtimeSync.ts` wraps `postgres_changes` with an `applyItemEvent`
  reducer (INSERT/UPDATE/DELETE → next items[]) and a `subscribeToList` helper
  that awaits the SUBSCRIBED handshake before returning
- `/lists/[id]` subscribes in onMount, unsubscribes in onDestroy. Uses a
  `pendingTempIds` set to deduplicate own-mutation echoes against optimistic
  rows (matches by name+created_by+sort_order)
- Client-generated UUIDs for new inserts make the path idempotent: if the
  server response is lost and we retry, the second POST hits PK-conflict
  which the queue treats as success
- CHECKED section div now carries role="listitem" so Playwright locators
  follow the item across sections

2b.2 Offline queue
- `$lib/sync/queue.ts` — SyncQueue class backed by IndexedDB (idb), FIFO flush,
  MAX_ATTEMPTS=5 retry budget, PK-conflict-as-success short-circuit
- `$lib/sync/index.ts` — app-wide singleton, window.online listener flushes
  automatically, hydrateSyncState() at page load restores pendingOpsCount
- `$lib/stores/syncStatus.ts` — derived store (offline | syncing | synced)
  tracking navigator.onLine + queue depth
- SyncBanner component renders the offline/syncing indicator in the detail
  and session views
- handleAdd enqueues on failure instead of reverting, so an offline mutation
  keeps its optimistic row and syncs on reconnect

2b.3 Modo Compra
- `/lists/[id]/session/+page.svelte` — full-screen overlay (fixed inset-0
  z-50) that covers the sidebar while keeping the normal auth routing.
  56×56 toggles, flip animation shuffling items between TO BUY / CHECKED,
  Finish Shopping confirmation modal → completeList → goto('/lists')
- Link from `/lists/[id]` header (data-testid=start-session) with the
  new `list_start_session` message

Testing infra
- apps/web gets its own Vitest config (jsdom + fake-indexeddb/auto) and a
  new `pnpm test:unit` script. `just test-all` now chains pgTAP → integration
  → unit → e2e so a single command is the gate.
- packages/test-utils/tests/sync-queue.test.ts (placeholder scaffold) removed —
  replaced by `apps/web/src/lib/sync/queue.test.ts` co-located with the module

Totals: 103 tests green
  16 pgTAP
  59 Vitest integration (in packages/test-utils)
   6 Vitest unit (in apps/web — the SyncQueue)
  22 Playwright E2E (5 auth + 4 lists + 6 items + 2 realtime + 2 offline + 3 session)
   2 skipped (realtime-presence — upstream bug, unchanged)

Documented in plan/fase-2b and CLAUDE.md.

/**
* Offline-first mutation queue backed by IndexedDB.
*
* Every mutation (insert / update / delete) is written to `pending_ops` before
* being sent to Supabase. If the network is down (or the request fails), the op
* stays queued and is retried on the next `online` event or manual `flush()`.
*
* Design:
* - Ops are processed in insertion order (FIFO). Order matters: a DELETE on
* an id inserted in a prior op must happen AFTER the INSERT, or the server
* rejects it as "row not found".
* - Failed ops keep their place in the queue and increment `attempts`.
* - On flush, ops that succeed are removed. Ops that fail with a
* non-recoverable error (e.g. RLS denial, constraint violation) are dropped
* after `MAX_ATTEMPTS` to avoid blocking the queue forever.
* - Last-write-wins conflict resolution: when an UPDATE op targets a row that
* was modified remotely later, the server UPDATE succeeds and the remote
* row ends up matching the local intent (or the user's change is lost —
* acceptable per the functional spec for MVP). A `sync_conflicts` row is
* written when an UPDATE's before-image differs from what we last saw; this
* is advisory only and does not rollback.
