feat(invoices): bulk Bokfor, per-view filter counts, review-queue draft CTA (#1533)

* feat(invoices): bulk Bokfor, per-view filter counts, review-queue draft CTA

Customer feedback: MCP-created invoices land in Granskning and then sit as
unnumbered drafts that each need individual issuance, and the list filter
gives no signal about where the work is.

- New POST /api/invoices/bulk-book: drafts get an F-number + mark-sent
  semantics (no email) and book inline when the company books at issue;
  sent/overdue unbooked invoices get the deferred /book semantics.
  Sequential loop keeps voucher numbers ordered; per-item Swedish errors.
- Extracted the shared cores into lib/invoices/issue-and-book-invoice.ts
  and lib/invoices/book-invoice-deferred.ts, now used by the per-id
  mark-sent and book routes AND the bulk loop, so they cannot drift.
  Per-id route behavior unchanged (existing route tests untouched, green).
- Invoice list: multi-select with hover-reveal checkboxes (supplier-invoices
  shape), bulkbar with mode-aware action label, ConfirmationDialog with a
  draft/sent breakdown, one aggregate toast. Kontantmetoden hides selection
  entirely.
- ContextPicker: count annotations on every status view via the one shared
  predicate (counts always match rows), active view written back to the URL
  (?status=) for shareable views. No seg/chip row: founder-locked pattern.
- Granskning: after a bulk approve that committed create_invoice ops, the
  summary toast links to /invoices?status=draft to finish with bulk Bokfor.

Verified: npm run lint clean, npm test 13845 passed, npm run check:guards
passed. New tests: bulk-book route (11), issueAndBookInvoice (7),
bookInvoiceDeferred (7).

* fix(invoices): bulk-book review findings, deferred drafts, dupes, URL params

- Deferred-booking companies (accrual + defer_invoice_booking): a draft in
  bulk-book no longer gets silently ISSUED (F-number consumed, marked sent,
  invoice.sent emitted) while reporting status 'booked' with a null
  journal_entry_id. The draft branch now requires booksInvoicesOnIssue();
  otherwise the item fails per-row with the new INVOICE_BOOK_DEFERRED_DRAFT
  code (Swedish + English) before the invoice is touched.
- Duplicate ids in one request no longer double-book: the second iteration
  read the stale pre-loop snapshot, passed the already-booked check, and
  minted a voucher the CAS claim then cancelled (cancelled verifikat + gap
  explanation per duplicate). Ids are deduped before the loop.
- Bulkbar: the select-all link is hidden when the current view has no
  selectable rows; "Markera alla (0)" only wiped the existing selection.
- Invoice dialog open/close handlers (new invoice, self-billed, ROT/RUT
  payout) rewrite only their own query keys instead of hardcoding
  '/invoices', so the ?status= view write-back survives them.
- /pending: the "Bokfor utkasten" toast CTA is suppressed for kontantmetod
  and deferred-booking companies where the invoice list offers no draft
  bulk Bokfor (dead end); the neutral hint sentence stays.

Tests: deferred-draft rejection (asserts issueAndBookInvoice never called,
sent invoice in the same batch still books) and duplicate-id dedupe (exactly
one booking call); both fail without the route fix.
