Each achievement row now carries a Tooltip whose text is derived from
the row's unlock state and the AchievementDef's reward, surfacing
information the row layout doesn't already show.
Four-state policy:
- Unlocked + reward → "Reward: <reward>." (e.g. "Reward: Card Back #1.")
- Unlocked + no reward → "Earned!"
- Locked, non-secret → "How to unlock: <description>." plus
" Reward: <reward>." when one exists
- Locked, secret → no tooltip; the existing row-spawn skip preserves
the achievement's discovery surprise
The row spawn loop tags each row with a new AchievementRow marker so
tests can locate them; the helper tooltip_for_row keeps the policy in
one place.
Six tests pin the policy: one full-flow test for unlocked + reward
mention, one secret-row negative test that asserts no tooltip
contains the verbatim secret condition or the secret reward, plus
four direct unit tests on tooltip_for_row covering all four states.
