Suggestion: Use Active Character's league for Vendor Recipes

[WhiteFang5]

🚀 feature request

Is your feature request related to a problem? Please describe.

Players in a SSF league cannot use the vendor recipes part of the tool due to not being able to select a SSF league in the leagues dropdown.

Describe the solution you'd like

Base the league used for stashes (required for vendor recipes) on the active character (selectable in the settings menu) instead of the selected league in the dropdown.

Describe alternatives you've considered

a. allow selecting of SSF leagues in the leagues dropdown (could be confusing for other parts of the overlay though?)
b. a separate "override league" dropdown for vendor recipes
