Disallowed checking out components to different companies and fixed number remaining counts

[marcusmoore]

Description

This PR fixes two issues when full multiple company support was enabled:

• Components were able to be checked out to assets belonging to different companies than the company the component belonged to.
• The "number remaining" (in the table and on the individual page) would show an inaccurate count for non-admins in the cases where components were checked out to assets belonging to a company different than the user's.

The scenario in pictures...

Two companies with the ids of 9 and 10:

Two components, one for each company:

Three assets assigned to three companies, including one that is not associated with a component above:

The component_assets table that shows components assigned to assets.

Only id:9 should be valid since only asset:2 is part of company:9 (Company A in text)

Acting as a super admin I can accurately see the remaining counts before and after this PR:

But as an admin for Company A (id:9) I see there are 4 remaining (should be 2):

After this PR the user sees the correct amount:

In addition, we can no longer check out a component to an asset that is not part of the same company when FMCS is enabled:

Should address the issues mentioned in #15212.

• Improved Logic in Store Method
  The store method in ComponentCheckoutController.php has evolved, with a new conditional check helping to bolster its functionality.

• More Precise Asset Tracking in numCheckedOut Method
  The counting of checked-out assets in Component.php has been refined due to the removal of the global scope, allowing for more accurate tracking.

• Namespace Update in Test Case
  The namespace in ComponentsCheckoutTest.php has been updated to keep the accuracy of references and identify potential errors early.

• Enhanced Company Support in Component Checkout
  A new test has been added within ComponentsCheckoutTest.php, allowing better checking for checkout across different companies when full company support is activated.

• Redirect Option for Component Checkout
  A new test within ComponentsCheckoutTest.php now also ensures that the redirect option to the 'index' setting for the component checkout page works as expected.
