feat(mental-health): one check-in pattern for every questionnaire, worded as published

Every instrument now runs the same wizard: the form's own question stem
above each item (the PHQ-9 and GAD-7 stems were missing), the item's
exact answer options as one radio group in source order, progress, Back,
number-key answers, and a review step that lists every answer, lets any
of them be changed and is the only step that submits. The result leads
with the crisis card when it applies, then shows the score on the
instrument's scale, the band, what the band means, the change since the
last check-in against the meaningful-change threshold, and the next
step. Scoring is untouched.

The wording was read against the published versions. German follows the
PHQ-D and Löwe's GAD-7 verbatim, including the follow-up question in its
published formal address. Spanish, Italian and Polish carry the official
PHQ-9 and GAD-7 translations, French the official GAD-7, and the GAD-7
gets its own answer set because the Italian forms word it differently.
Where a version could not be matched to a published form (the French
PHQ-9, every Korean form) the language now shows the English original.
Each locale list names its sources, and spot checks pin the corrected
wording.
