Add domain level to wave gridded COM path

[AntonMFernando-NOAA]

Description

• This pull request addresses the organization of wave gridded products within the file structure. Currently, all wave gridded products are placed in products/wave/gridded, without any further categorization. To align with the structure used by other component products (such as grib2), this update introduces a domain/resolution directory level to group output more effectively.

• For example, instead of having all products in a single directory, the structure will now include specific directories based on domain and resolution (e.g., products/wave/gridded/arctic.9km, products/wave/gridded/global.0p16). This change improves organization and scalability for wave gridded product outputs.
