fix(invoice-inbox): read whole PDFs (last-page slice + truncation retry) (#2014)

* fix(invoice-inbox): read whole PDFs (last-page slice + truncation retry)

PDF extraction read only part of well-structured PDFs, two confirmed
mechanisms (21-day prod window: 49 sliced docs, 29 silent empties):

- The auto-extract page budget was 3 (Bedrock-latency legacy, issue #553)
  and the slice kept only the first pages, so multi-page invoices lost the
  final page where totals, OCR and 'Att betala' sit. The budget is now 8 on
  pdf-native backends (Claude reads PDFs directly); the slice always keeps
  the last page. Rasterizing self-host backends keep the old budget of 3.
- A max_tokens-truncated model answer was parsed as-is, failed, and became
  an all-null extraction with no trace. extractFromDocument now reports
  stop_reason max_tokens / finish_reason length as truncated; the extractor
  retries once at double AI_EXTRACTION_MAX_TOKENS and logs
  ai_extraction_truncated either way.

* fix(invoice-inbox): sweep cutoff covers the slower two-call extraction

Skeptic finding on #2014: the crash-recovery sweep flipped 'processing'
rows to an empty skeleton after 2 minutes, but a deferred extraction can
now legitimately run 3-5 minutes (8 native pages plus one truncation
retry at a doubled token cap), so the sweep stole the row and the CAS
discarded the worker's real result. Cutoff raised to 10 minutes.

Also: pages_partial_note made period-agnostic (old rows were extracted
from first-pages-only slices, so naming the last page was retroactively
wrong for them), and two stale first-pages-only comments updated.

* fix(invoice-inbox): keep the first extraction response when the retry throws

CodeRabbit finding on #2014: a throttled/failed retry call bubbled to the
outer catch before rawText was assigned, discarding a first response whose
text may parse fine despite the truncation flag. The retry is now caught
locally (logged as ai_extraction_retry_failed) and the first result flows on.
