feat(articles): server-side bulk-import worker (Phase 2)

Browse source 
apps/api/src/modules/articles/:
  - import-projection.ts: sync_changes → live LWW projection of jobs
    + items. Cross-user scan for claimable jobs, per-job item scan.
  - import-extractor.ts: per-item state-machine. Claim → fetch → write
    pickup + flip extracted, OR retry up to 3x then 'error'. All writes
    attributed to system:articles-import-worker actor (built inline so
    no shared-ai SystemSource extension needed for now).
  - import-worker.ts: 2s tick, pg_try_advisory_xact_lock keyed on 'ARTI'
    so multi-instance apps/api never double-processes. Concurrency 3
    pending items per job per tick. Job-counter rollups + status flips
    derived from current item states.
  - apps/api/src/index.ts: start the worker at boot.

Pipeline (server side):
  Client write articleImportItems(state='pending')
    → sync push → mana_sync.sync_changes
    → server-worker tick projects 'pending' items
    → extractFromUrl (shared-rss / Readability)
    → write articleExtractPickup row + flip item → 'extracted'

Phase 3 (client-side pickup consumer) and Phase 4+ (store + UI) follow.

Plan: docs/plans/articles-bulk-import.md.

/**
* Articles Bulk-Import — per-item extraction + write-back.
*
* For one `articleImportItems` row in state='pending':
*
* 1. Flip to state='extracting' (so other ticks / the UI see progress).
* 2. Run `extractFromUrl` against the URL.
* 3a. On success → write a `articleExtractPickup` row carrying the
* full ExtractedArticle payload + flip the item to 'extracted'.
* The client-side pickup-consumer picks it up, encrypts the
* article into the user's IndexedDB, and flips the item to 'saved'
* (or 'consent-wall' if the warning fired).
* 3b. On failure → bump `attempts`, flip back to 'pending' if
* attempts < 3, else flip to state='error' with the technical
* error message.
*
* Every state-change is one `sync_changes` row attributed to the
* `system:articles-import-worker` actor (built inline below — kept out
* of the shared-ai SystemSource union for now to keep the worker self-
* contained; can be hoisted later). Origin is `'system'` so the
* conflict-detection gate on the client doesn't surface these as
* user-visible toasts.
