BytePlus pricing: images section parses 0 rows every poll (parser_miss since 2026-11-12 06:01) #640

BytePlus pricing is failing on every poll:

• 2026-11-12 06:01–18:16 UTC: 400 pricing_lost events with reason parser_miss.
• From 18:31 UTC on, every models poll fails with byteplus pricing page (images): parsed 0 model rows (19 ingest_failed events, latest 23:01).

The public ModelArk pricing doc that src/server/providers/byteplus-pricing.ts parses appears to have changed. The images section no longer yields any row, and before that the chat rows were missing.

Fix: re-read the current page, update the parser for the new layout, and keep it fail-closed. No fallback prices. A page that parses nothing still throws. Add a fixture from the current page.
