fix(pcap): preserve exact UTC capture instants

Request epoch timestamps from capinfos and normalize them once at the
metadata boundary, preserving nanosecond precision and explicit unknowns.
Bound numeric parsing to the producer representation and cover negative
fractions, calendar limits, malformed output and MCP projection.

Adapted from PR #4909. Fixes #4907.

Validation: 47 passed, 24 platform-specific skips across five focused
files; check:fast and test discovery passed. No live Wireshark or
Linux/Windows capture execution was performed on this macOS host.
