feat(fees): adult rates for 2026-07 to 2026-12, default 600

- Default adult monthly rate 700 -> 600 CZK
- 2026-07 and 2026-08 set to 0; 2026-09 through 2026-12 added at 600
- Single-session fee is capped at the month's rate, so a 0-rate month
  is free for one session as well
- Mirrored in Go and legacy Python; new calculate_fee parity fixtures

### Member tiers
Tiers are set in column B of the attendance sheet:
- `A` — Adult, pays fees (per-month rate from `AdultFeeMonthlyRate` / `ADULT_FEE_MONTHLY_RATE`, fallback 700 CZK for 2+ sessions; 200 CZK for exactly 1)
- `A` — Adult, pays fees (per-month rate from `AdultFeeMonthlyRate` / `ADULT_FEE_MONTHLY_RATE`, fallback 600 CZK for 2+ sessions; 200 CZK for exactly 1, capped at the month's rate)
- `J` — Junior attending adult practices; their attendance is merged with the junior sheet
- `X` — Excluded from junior fee calculation (coaches, etc.)
### Fee calculation
- Adults: 0 sessions → 0, 1 session → 200 CZK, 2+ sessions → monthly rate (default 700 CZK)
- Adults: 0 sessions → 0, 1 session → 200 CZK (never more than the month's rate, so a 0-rate month is free), 2+ sessions → monthly rate (default 600 CZK)
- Juniors: 0 → 0, 1 → `"?"` (manual review required), 2+ → monthly rate (default 500 CZK)
- Per-member per-month overrides live in the `exceptions` tab of the payments sheet (columns: Name, Period YYYY-MM, Amount, Note). Exceptions are keyed by `(normalize(name), normalize(period))`.
