Review Comment:
   These v1 datetime helpers still call 
`fromJavaDateType(toJavaDateType().plus...)` with one argument. After this 
change, `DateTimeLiteral` no longer defines that overload, so those calls 
resolve to the inherited `DateLiteral.fromJavaDateType(LocalDateTime)`, which 
constructs a date-only literal. For example, `new DateTimeLiteral("2024-01-01 
12:00:00").plusHours(1)` now returns `2024-01-01` instead of a v1 datetime 
preserving `13:00:00`; `TimeRoundSeries.getDateCeilOrFloor` can then return 
`null` because it requires `result instanceof DateTimeLiteral`. Please restore 
the one-argument `DateTimeLiteral` overload or update the v1 `plus*` helpers to 
call this two-argument overload, and add a focused v1 datetime 
arithmetic/rounding test.
