`pages_embedded` carried an interim chunk count (`len(chunk_texts)`,
TODO #282). Reframe it as a charge for *parsing* (PDF page extraction /
OCR) rather than a normalized content size:
- Parsed files (PDFs) record `pages_embedded` = real `page_count` from
the document processor metadata.
- Text content (notes, deck cards, news items) is never parsed, carries
no `page_count`, and records no `pages_embedded` row — only
`tokens_embedded`. There is deliberately no chars/tokens-per-page
constant; pages map 1:1 to parsed document pages.
`record_indexing_usage` now takes `page_count` and records the two
dimensions independently, gating `pages_embedded` on a truthy page count
(not the doc_type) so a future non-PDF parsed type stays correct. Stays
flag-gated + best-effort. Tests cover parsed-file, text-only, and
zero-page cases.
Deck #282 (board 8). Billing-model ADR corrected in
astrolabe-cloud-website docs/control-plane/usage-metering.md.
