Replaces the radio+continue layout with a Steam Cloud Conflict
lookalike: uppercase title with circled-! glyph, three-line body
copy, two large card-buttons (Cloud Save / Local Save) each showing
icon + label + 'Modified <date>', Cancel bottom-right. Card click
commits the choice and dismisses — no separate Continue button.
Background switched to Steam-blue (#1b2838) instead of Prism dark
so the dialog reads as a 'pay attention' moment rather than another
status pane.
Card glyphs are unicode placeholders (☁ / ▢) — easy SVG swap later
if we want crisp HDD/cloud icons.
API change:
prompt_conflict_qt(local_summary, remote_summary)
→ prompt_conflict_qt(local_modified, remote_modified, save_label)
Caller now passes pre-formatted timestamp strings + an optional
noun phrase ('Minecraft save').
