Final pre-reset calibrations

A batch of fixes and tweaks important for upcoming game reset. Economy rebalancing and few things I've noted along the way but held off on until the economy decisions were settled.

• CHANGE Economy adjustments

  • reduced academy investment to 100k/week to weaken no-academy strategy
  • increased salaries from ~120k after reset to ~240k to counter balance reduced academy cost
  • reduced friendly income by 30% to max ~1M/season
  • single academy scout is no longer 2x expensive as weekly salaries
  • those changes prepare ground future adjustment (e.g. medical staff, non-linear salaries and others)

• CHANGE Fixed an unrealistic height distribution — players over 220cm made up about 2.5% of the population (124 out of 4900 in production), versus under 0.5% in the real NBA (just 3 players). Adjusted the seeding algorithm to match roughly 0.5%

• CHANGE Improved the wide age-spread issue in generated teams, reported by @grillo94. Starting lineups will now get one player from each of ages 24, 25, 26, 27, and 28, randomly allocated to positions — same approach for bench players at ages 22, 24, 26, 28, and 30

• FEATURE More diverse play-by-play commentary — multiple text variations per event type, proposed by @coach_r

Before the reset, attention shifts to the engine to address feedbacks I got from @d
