- Extract AssembleJuniors(ctx) from ServeJuniors JSON handler so HTML
and JSON share the same view-model path (mirrors AssembleAdults pattern)
- Add JuniorsPageData wrapper in render.go
- Wire HTMLHandler.ServeJuniors to AssembleJuniors + render template
- Replace 4-line placeholder juniors.tmpl with full template:
member table, name filter, month-range filter, totals row,
Credits + Debts sections, Pay / Pay All buttons via /qr links
(no Unmatched section — matches Python juniors.html parity)
- J/A attendance breakdown ("3/500 CZK (4:2J,1A)") and "?" sentinel
rendered via MonthCell.Text from buildJuniorMemberRow, no extra
template logic needed
- All tests pass; make parity reports 3/3 routes OK
