Review Comment:
   Reopening this one briefly, @rusackas. On the dataset path I do not think it 
is covered: by the time `_serialize_query` runs, `_apply_granularity` has 
already deleted the `TEMPORAL_RANGE` entry from `QueryObject.filter` (it fires 
whenever `granularity` names the filter's column, which `query_dataset` always 
does when `time_range` is set), so there is nothing left for 
`convert_legacy_filters_into_adhoc()` to convert. I verified it on the head: 
after the real factory, `queries[0].filter` is `[]` and `get_time_filter()` 
returns `No filter`. Details and a suggested fix in my comment on 
`query_dataset.py`. Are the chart tool paths safe only because their 
`form_data` carries a top level `time_range`, or is there another mechanism I 
am missing for the column specific case there?

Review Comment:
   First, the cache side of 5ca36d0 checks out, and I verified it in both 
directions on this branch: two explicit ranges produce different 
`QueryObject.cache_key()` values through the real `QueryContextFactory`, 
identical ranges share one key, and 
`test_query_dataset_reexecutes_across_rollover` fails at 3d17c49 and passes 
here. So the rollover regression from putting `time_range` on the `QueryObject` 
was real and this commit fixes it. Nice catch.
   
   This comment block worries me a bit though: the claim that Jinja 
`get_time_filter()` still sees the range via the `set_query_context_form_data` 
hoist does not hold on this path. `QueryContextFactory.create()` runs 
`_apply_granularity`, and because `query_dataset` always sets `granularity` to 
the same column carrying the `TEMPORAL_RANGE` filter, that filter is deleted 
from `QueryObject.filter` before `execute_tabular_query` reaches 
`set_query_context_form_data`. I verified it on this branch: after the real 
factory runs, `queries[0].filter` is `[]`, `time_range` is `None`, and 
`ExtraCache().get_time_filter().time_range` renders `No filter` instead of the 
requested `Last week`. The same sequence at 3d17c49 rendered `Last week`.
   
   The new tests pass because they never run `_process_query_object`: 
`test_query_context_form_data_hoists_time_range_from_temporal_filter` builds 
the `QueryObject` by hand with the filter still attached, and 
`test_query_dataset_exposes_filters_to_jinja_macros` patches 
`QueryContextFactory.create` with `_query_context_from_factory_kwargs`, which 
skips `_apply_granularity` entirely.
   
   Not a blocker on its own, master never exposed the range to Jinja on this 
path either, so nothing regresses against master. But the comments here and in 
`build_query_dict` document a mechanism that does not fire, and Jinja alignment 
is the point of this PR. Since a rebase is needed anyway, could we make the 
hoist real in the same pass? `QueryContext` keeps the raw pre-processing query 
dicts in `cache_values["queries"]`, so `set_query_context_form_data` can fall 
back to those when the processed query lost the filter:
   
   ```python
   raw_queries = (getattr(query_context, "cache_values", None) or 
{}).get("queries") or []
   ```
   
   and hoist via `_time_range_from_filters(raw.get("filters"))` per query. Then 
turn `test_query_dataset_exposes_filters_to_jinja_macros` into a real factory 
test (patch `QueryContextFactory._convert_to_model` instead of `create`) so the 
assertion actually exercises `_apply_granularity`; that variant fails on the 
current head, which is exactly the coverage we are missing. Happy to dig in 
with you if it helps.
