QA flagged 'gaming laptop' returning a CARBONADO Backpack as the #1 result. The product title literally contains 'Gaming Laptop' and 'Laptop', so the existing BUY-62409 laptop-multiplier (2.0x on title LIKE '%laptop%' for the top_ids FTS CTE) was firing on backpack SKUs. The accessory exclusion list in that branch already covered sleeve/case/bag/stand/pad/cooler/adapter/ dock/hub/lock/briefcase/charger/table but not backpack/accessory keywords, so the backpack was outranking actual gaming laptops. This change extends the FTS ranking top_ids CTE to also negate backpack, accessories, replacement, battery, mouse, keyboard, headset, monitor, etc. from the laptop-boost branch. A backpack titled 'Gaming Backpack For Laptop, Gaming Laptop and Gaming Accessories' will no longer match the 2.0x boost and will rank behind actual gaming-laptop SKUs (RTX-series notebooks, ASUS ROG, Lenovo Legion, GIGABYTE A16). Also includes the BUY-63505 accessory-demotion refactor that hoists the shared accessoryDemotionSql expression so SEO/laptop/general fallback queries all use the same demotion terms, plus a new regression-guard test (BUY-65156) in tests/ts-rank-guard.test.mjs.

Summary
QA flagged 'gaming laptop' returning a CARBONADO Backpack as the #1 result. The product title literally contains 'Gaming Laptop' and 'Laptop', so the existing BUY-62409 laptop-multiplier (2.0x on title LIKE '%laptop%' for the top_ids FTS CTE) was firing on backpack SKUs. The accessory exclusion list in that branch already covered sleeve/case/bag/stand/pad/cooler/adapter/dock/hub/lock/briefcase/charger/table but not backpack/accessory keywords, so the backpack was outranking actual gaming laptops.
Fix
Extends the FTS ranking top_ids CTE in api/src/routes/products.ts to also negate backpack, accessories, replacement, battery, mouse, keyboard, headset, monitor, etc. from the laptop-boost branch. A backpack titled 'Gaming Backpack For Laptop, Gaming Laptop and Gaming Accessories' will no longer match the 2.0x boost and will rank behind actual gaming-laptop SKUs (RTX-series notebooks, ASUS ROG, Lenovo Legion, GIGABYTE A16).
Also includes the BUY-63505 accessory-demotion refactor that hoists the shared accessoryDemotionSql expression so SEO/laptop/general fallback queries all use the same demotion terms.
