feat: /sync settings page with price multiplier and description postfix

Adds price_multiplier and description_postfix to SyncConfig. The sync
page at /sync lets users configure them. vk_sync reads these per-user
settings and applies the multiplier to price and appends the postfix
as "(postfix)" to the VK product description.
