- teams.service.spec.ts: pick a checkpoint older than the adjustment's own
month so the exclusion test actually fails without the exclusion filter
- teams.service.ts: only negate fine/levy/fee amounts when positive,
matching TeamMembersService.recomputeBalance and Transaction.setBalance()
exactly, instead of negating unconditionally
- teams.service.ts: outstanding-history helper now returns a positive
value when players owe money, matching the house convention already
established by getOverview()'s team.outstanding
- overview.spec.ts: assert the balance chart's legend becomes visible
- teams.service.spec.ts: add coverage for inactive-player exclusion and
a positive-balance (prepaid credit) case

Reconstructs each active player's balance per month (same backward
technique as the existing cash-balance history) so the overview stats
endpoint can report what the team balance would be if all currently
open dues had already been paid.
