[Creylay]

Summary

Fixed the session info modal getting cut off with no scroll when its content was too long, and added an "Applied Converters" section to it (same style as input/output columns).

Changes (by file)

• shared/InfoModal.jsx: the modal's outer container now caps its height at 85vh and lays out as a flex column, the header no longer shrinks, and the body scrolls on its own (overflowY: auto, flex: 1, minHeight: 0), so long content no longer gets cut off with no way to reach it.
• models/SessionInfoContent.jsx: added an "Applied Converters" section between "Session Configuration" and "Metadata", shown only when the session has preprocessing steps. Each step is rendered as a ParamInfoBox (same style as input/output columns), with its display name and scope resolved through the existing buildStepDisplayNames and buildColumnKeysAndTypes helpers, so a converter's name and its referenced columns (raw or chained from an earlier step's output group) show exactly as they do in the rest of the session wizard.
• utils/i18n/locales/{en,es,de,pt,zh}/models.json: added the appliedConverters label key used by the new section.

Testing (optional)

• Manually verified: a session with several converters no longer gets its info modal cut off, and the new section lists each converter with its resolved scope columns.
