Subfleet and Aircraft Expenses Being Applied to Wrong Airline

[FatihKoz]

Subfleet and Aircraft based expenses are being applied to all airlines, even to airlines without subfleets/aircraft.

Version 7.0.0-dev+231215.655f15

To Reproduce Steps to reproduce the behavior:

1. Go to Admin > Fleets, pick one subfleet and click edit
2. Add some daily expenses to the subfleet
3. Either wait for daily cron to run at midnight or force run it
4. Check your cron log, you will see that the expense is applied to other airlines and subfleets too (!)
5. Also check your finances, or better transactions, you will see that the expense is applied at all assets (!)

Expected behavior Daily / Monthly expenses should be applied to relevant subfleets / aircraft, not to all.

Additional context Looks like there are logical problems while picking up proper objects.
