feat(contact): add 'etc' (기타) product option

Adds 'etc' as the 8th enum value in PRODUCT_IDS with label '기타',
covering inquiries that don't fit the 7 solution products. Routes to
first-fluke/first-fluke.github.io via PRODUCT_ROUTES env on the Worker
(operator config — already provisioned).

Reverses ADR-0001 D2's prior 'no etc option' choice; ADR and task.md
updated in the outer repo.
