[BlueberryKing]

Fixes #[issue_no]

Summary of Changes

• Sort runways alphabetically in departure/arrival selection screen
• Fix not all runways being selectable as runway-only approaches because the list was too short
• Make "Return" button on lateral and vertical revision pages return to the previous flight plan position rather than the top

Testing instructions

• Check departure/arrival runway selection is sorted alphabetically
• Check you can select all runways as approaches (no instrument approach, just the runway)
• Go to the lat/vert rev page from the flight plan page, ensure that pressing "Return" puts you back to the original position on the flight plan page

This will sort parallel runways in C, L, R order. Are we sure it shouldn’t be L, C, R?

It is correct according to this reference, but I'm happy to adjust this if it has been changed in newer versions of the FMS.

Nope, that’s perfect 👌.
