Extract shared types and add Regulation type with parsing methods

Move cookie banner types (CookieItem, Category, Regulation, BannerConfig,
etc.) into a dedicated types.ts file. Add a coredata.Regulation type with
parsing, JSON marshaling, and database scanning methods. Hardcode the
geoloc-import data directory since the submodule path is fixed.
