[FEATURE] Allow scoring overhead and underseat bags simultaneously as a combo #4
Description
Problem Description
My recent use case: I wanted to check if my 40 x 20 x 55 cm roller and my new backpack will both be OK-ish before I buy later, without tweaking numbers or switching between bags. Right now, I have to either change the bag dimensions over and over or open multiple tabs to test each bag separately, which is a bit annoying and easy to mess up. It would be much nicer if I could just enter both bags once and see how they behave together across airlines.
Proposed Solution
Add a simple "two bags" mode where one can enter dimensions for a cabin bag and a personal item at the same time and then see if that specific pair is allowed for each airline. The results list should show clearly for every airline whether the cabin bag fits, whether the personal item fits, and whether the overall combination is accepted or not.
The current mode with a single bag should also be changed to support scoring it as just carry-on, just personal items, or both. If a single bag is just scored as a specific type of cabin luggage, the airline card should be shown as failed if the user's bag dimensions don't fit the specific kind of luggage.
To improve visibility when one dimension is passed or failed, for a single or combo mode, it would be better to have some status text for compliance: Passed, Failed, or Skipped.
Also, because there's already a soft bag size deviation mechanism after #14, it should be separated for each bag.
