T3333 — MyCompassion "write a letter" quality-test failures

Original ask

A quality test on "MyCompassion: write a letter" failed on 2026-07-22 with several defects reported from a single manual walkthrough:

• No menu icons top right, child picture missing, child arrow selector missing, Compassion logo missing top left, on the new-letter page.
• No margin under the "Preview"/"Send" buttons.
• Saving a draft shows a green "letter saved" confirmation in English instead of the sponsor's language.
• The letter preview's attached-pictures page showed "Additional pictures" in large block capitals.
• Opening a just-sent letter from MyCompassion gave an internal server error.
• Backend → Sponsorships → Correspondence → Letters → a letter → action wheel → "Correspondence Report" downloads the PDF instead of displaying it, on Mac.

What changed

compassion-website (my_compassion)

• ffb58fc — added a bottom margin below the Preview/Send button row (was flush against the footer) and a gap between the letter textarea and the attachments upload box below it.
• a6ab2c1 — the autosave success toast (fires automatically on form changes, e.g. changing the template) used a raw JS string instead of _t(), unlike the near-identical toast on an explicit "Save draft" click — so it always showed in English regardless of the sponsor's language. Wrapped it and added the translation to all 8 locales my_compassion ships (da_DK, de, fi_FI, fr_CH, it, nb_NO, pl_PL, sv_SE), matching each locale's existing "draft" terminology.
