Extracted from ObservedCsvRunLayer::parseRow_ so the same parser drives:

• file import (ObservedCsvRunLayer, TimeseriesProvider ExternalFile mode)
• clipboard paste into the TimeseriesEditorDialog grid

Supported time formats (tried in order, mirrors legacy + ObservedCsvRunLayer):

• ISO 8601: yyyy-MM-ddTHH:mm:ss, yyyy-MM-dd HH:mm[:ss], yyyy-MM-dd
• SWMM .dat / US: MM/dd/yyyy [HH:mm[:ss]]
• European: dd/MM/yyyy HH:mm
• 12-hour US AM/PM: M/d/yyyy h:mm[:ss] AM|PM (PCSWMM .tsf; single-digit month/day/hour accepted, 24-hour siblings included)
• Hours-since-start: numeric fallback (only when fallbackBase is finite)

Auto-detected delimiters: tab, comma, semicolon (highest-count wins; defaults to comma when none are present).
