Preserve complete records in iOS artifact parsers

[besendorf]

Summary

• Preserve complete source rows in Calendar, Calls, Contacts, DataUsage, InteractionC, Safari history, TCC, and WebKit resource statistics while retaining their established top-level fields.
• Preserve binary and date values in JSON-compatible form instead of dropping columns.
• Keep Safari tabs that do not have a matching session row and retain complete tab metadata.
• Retain contacts without multivalue entries.

Compatibility

Existing serialized fields and timeline behavior remain available; complete source data is added under nested record fields.
