H3 index bug

When using the H3 index, in some cases, the correct filtering of distances is not possible.

## Test case
### Data

#### geodata.csv
```csv
name,lng,lat
a,-103.34056886616187,20.63611463218247
b,-103.31104310932645,20.606231326034603
c,-103.33524736347661,20.595626162929634
```
#### schema
```json
{
"metricFieldSpecs": [],
"dimensionFieldSpecs": [
{
"dataType": "STRING",
"name": "name"
},
{
"dataType": "FLOAT",
"name": "lng"
},
{
"dataType": "FLOAT",
"name": "lat"
},
{
"dataType": "BYTES",
"name": "location_st_point",
"transformFunction": "toSphericalGeography(stPoint(lng,lat))"
}
],
"schemaName": "geodata"
}
```

#### table

```json
{
"tableName": "geodata",
"tableType": "OFFLINE",
"segmentsConfig": {
"retentionTimeUnit": "DAYS",
"retentionTimeValue": "1",
"segmentPushType": "APPEND",
"segmentAssignmentStrategy": "BalanceNumSegmentAssignmentStrategy",
"schemaName": "geodata",
"replication": "1"
},
"tenants": {
},
"fieldConfigList": [
{
"name": "location_st_point",
"encodingType": "RAW",
"indexType": "H3",
"properties": {
"resolutions": "7"
}
}
],
"tableIndexConfig": {
"loadMode": "MMAP",
"noDictionaryColumns": [
"location_st_point"
]
},
"metadata": {
"customConfigs": {
}
}
}
```

### Query
```sql
select name,
lat,
lng,
ST_DISTANCE(
location_st_point,
ST_Point(-103.34417375507813, 20.64061268636347, 1)
) as distance
from geodata
where ST_DISTANCE(
location_st_point,
ST_Point(-103.34417375507813, 20.64061268636347, 1)
) < 5000;
```
### Query Response
```csv
name,lat,lng,distance
a,20.636114,-103.34057,625.2019871997669
b,20.606232,-103.31104,5148.1557916677875
c,20.595627,-103.33525,5087.813601469894
```

## Analysis
**This appears to be a problem with KRing calculations***

### Code
https://github.com/apache/pinot/blob/e3d238ac1d8633331d9507713266e41e6b40f870/pinot-core/src/main/java/org/apache/pinot/core/operator/filter/H3IndexFilterOperator.java#L186-L198

### Visualize

Start in pinot-core/src/main/java/org/apache/pinot/core/operator/filter/H3IndexFilterOperator.java at the linked KRing calculation around lines 186-198. Reproduce the supplied geodata schema, H3 resolution 7, and ST_DISTANCE query, then inspect how the candidate cells are selected. Done means the query returns only rows within 5000 meters while preserving the expected nearby result.
