Removed unneeded Company::scopeCompanyables from ReportsController

This PR simply removes Company::scopeCompanyables from the ReportsController since the Asset model already has the CompanyableTrait on it.

Another small step in the direction of simplifying how models are scoped to companies.

PR Summary

• Updated Asset Selection in ReportsController
  Our ReportsController file has changed how it manages the selection of certain assets. This means the system might operate differently when gathering and presenting data for these assets.

• Additional Permission Control in UserFactory
  Our UserFactory file now includes a 'canViewReports' method. This update directly affects how users' permissions are identified and allocated when it comes to viewing reports. In simpler words, it's a new rule to decide who can see what sorts of reports.

• New Testing for Custom Reports
  We've introduced a new file named CustomReportTest. This file contains tests that specifically focus on generating custom asset reports. This is part of our ongoing efforts to make sure the new system for customized report generation is working as expected.
