* fix(promql): accept evaluation times before the Unix epoch
Prometheus accepts negative timestamps in query parameters; GreptimeDB
rejected them while parsing and would panic converting them in the planner.

* test: update flow_tql error for a negative TQL end time
A negative end now parses and fails the end >= start check instead of
the timestamp conversion.

* fix(promql): reject evaluation times outside the millisecond range
The signed millisecond conversion cast u128 to i64 unchecked, so a far-past
time wrapped into the future. Reuse the checked conversion from
label_values and return an error instead.

* fix(promql): round query times to milliseconds like Prometheus
Numeric times round the fraction of a second to milliseconds, and
pre-epoch times floor sub-millisecond parts, matching Prometheus'
parseTime and timestamp.FromTime.
