Sponsor types arrive, plus finances rework and a few fixes

A few quiet days on my side (due to chess, my 2nd hobby, greetings to all the chess players out there ♟️), but a solid batch of changes is now live.

• FEATURE Sponsor types, selectable during the first 5–6 days of each season. It looks simple, but it's a big change under the hood, so let me know if you notice any sponsor issues. This season every team runs on the "Stability" contract, and the first real choice comes in the opening days of Season 2
• FEATURE Form changes now show next to training changes in Training → Recent changes and on the player profile, proposed by @lolek131
• FEATURE Training planner is coming to the ⭐ Supporter package. You can preview it on the Supporter page
• CHANGE Finances reworked into tabs to make room for sponsors
• FIX Fixed the shortened Watch Live view, reported by @coach_r, @nhegas and @endru
• FIX Fixed outdated cup information, reported by @ettore_messina

Next up: a few fixes queued for the v4 engine, and finishing the League Watch feature.

📣 Reminder: the Promote BasketVibe program is still running. Share your link, vote for us on the listings, and top referrers may receive three months of Silver Supporter. I decided to grant supported package till the end of the year to @nawrot3g who brought 4 new players!
