World stats, a cleaner Club page, and a batch of fixes

Couple of changes delivered to production

• FEATURE World page now has an additional Stats tab, showing the top 20 leagues by Division Hardiness (DH) and top 20 teams by Team Strength (TS)
• CHANGE Removed the "Change bid" button from the Club page to keep it more compact
• FIX Fixed player history not showing players who were transfer listed — reported by @alvaradogoat
• FIX Fixed the "manager since" logic — @zhuchok
• FIX Fixed player generation producing unrealistic demographics for certain countries (e.g., Ukraine) — @zhuchok
• FIX Fixed a timezone display discrepancy between transfers and game kick-off times — UI now shows local time — @zhuchok

Special thanks to @grillo94 for a series of thorough, data-driven analyses of the game — including the new player generation algorithm. That kind of digging genuinely helps us catch things we'd otherwise miss.

Keep delivering ideas, and together we can build the best online basketball manager ever.
