fix: resolve advance decision and surface country on rankings list

The side panel only read Evaluation.binaryDecision, which is null when
the round's evaluation form stores the 'proceed to next round' answer
as a boolean criterion in criterionScoresJson (the current round's
shape). project.getFullDetail now resolves a unified `decision` field
per assignment using the same fallback pattern as the ranking router:
prefer the column, fall back to a type='advance' (or legacy 'move to
the next stage' boolean) criterion looked up by id in the active form.

Also: project country in the rankings list now renders whenever it's
present, not only when teamName is also set.
