refactor: use MaxPageSize constant as default pageSize across all frontend services

AlbumService.GetAlbumsAsync, AssetService.GetAssetsAsync, PersonService.GetAllAsync
now default to PagedParametersDto.MaxPageSize (250) instead of hardcoded 30.
Also fixed AssetService.GetAssetsAsync page default from 1 to 0 for consistency
with zero-based pagination.
