fix(scraper): implement Priméo Énergie PDF parsing instead of fallback

The Priméo scraper was always falling back to hardcoded values because
_parse_pdf() returned an empty list. This commit implements actual PDF
parsing that extracts prices directly from the Priméo tariff sheet:

- Parse concatenated PDF text by splitting on 'kVA' markers
- Extract BASE subscriptions (3-36 kVA) and kWh price (0.1327€ HT)
- Extract HC/HP subscriptions (3-36 kVA) with HP (0.1434€) and HC (0.1147€)
- Update fallback values to match current PDF prices (2025-12-05)
- Add 3 kVA option to HC/HP (Priméo offers it unlike standard TRV)

The scraper now returns 18 offers (9 BASE + 9 HC/HP) from live PDF data.
