The x axis zoom selector in the embed modal doesn't work

[SylvainChevalier]

The embeds don't have the zoom buttons anymore and that's fine.
But the embed modal still has a dropdown menu with zoom options, and that should work.

Fixed embed modal zoom selector

Root cause: The embed modal correctly adds a zoom URL parameter to the iframe URL, but the embed page (page.tsx) was not reading this parameter and passing it down to the chart components. The zoom dropdown selection had no effect on the rendered chart.

Fix: Reads the zoom search param in the embed page and threads the defaultZoom prop through the full component chain:

EmbedPage → EmbedScreen → EmbedQuestionCard → EmbedQuestionPlot → DetailedQuestionCard / DetailedGroupCard → chart components

The zoom parameter is validated against TimelineChartZoomOption enum values (1d, 1w, 2m, all) before being passed down.

• Gather context and identify root cause
• Parse zoom param in embed page (page.tsx)
• Pass defaultZoom through EmbedScreen
• Pass defaultZoom through EmbedQuestionCard
• Pass defaultZoom through EmbedQuestionPlot to chart components
• Pass defaultZoom into DetailedQuestionCard (binary, numeric, date, discrete, multiple choice)
• Pass defaultZoom into DetailedGroupCard (group questions, fan charts)
• Push changes

Files changed (7):

• front_end/src/app/(embed)/questions/embed/[id]/page.tsx — parse zoom from URL search params
• front_end/src/app/(embed)/questions/components/embed_screen.tsx — accept and forward defaultZoom
• front_end/src/app/(embed)/questions/components/embed_question_card.tsx — accept and forward defaultZoom
• front_end/src/app/(embed)/questions/components/embed_question_plot.tsx — accept and forward defaultZoom to both DetailedQuestionCard and DetailedGroupCard
• front_end/src/components/detailed_question_card/detailed_question_card/index.tsx — accept and forward defaultZoom to DetailedContinuousChartCard and DetailedMultipleChoiceChartCard
• front_end/src/components/detailed_question_card/detailed_question_card/multiple_choice_chart_card.tsx — forward defaultZoom to MultipleChoiceTile in embed mode
• front_end/src/components/detailed_question_card/detailed_group_card/index.tsx — accept and forward defaultZoom to MultipleChoiceTile and GroupTimeline
