Fix: validate 'start' parameter in parse_start and raise ValueError on invalid
formats
Improved input handling in parse_start by detecting invalid timestamp
strings and raising a clear ValueError instead of silently converting them.
This matches expected behavior in LogeventsPageGenerator and ensures
better consistency with test expectations.
