When a fixed date (e.g. 2027-01-01) is paired with a weekday constraint (e.g. Thu) that does not match, the timer silently never elapses. Add calendar_spec_from_string_full(..., warn_on_weekday_mismatch) so user-facing tools can opt in to a log_warning() at parse time: - systemd-analyze calendar: uses _full(true) - systemd-run --on-calendar: uses _full(true) - .timer OnCalendar=: uses log_syntax() with file/line context Add test_calendar_spec_weekday_conflict(): forks a child with stderr captured in a memfd via pidref_safe_fork_full(), verifies the warning is emitted for conflicting specs and suppressed for valid ones.
