Fix iModelGrid Filtering to Show Complete Results Across All Data

[Bentley-Vivek]

This PR fixes two issues with the IModelGrid component's handling of filtering via postProcessCallback:

1. Incomplete Results: The component was only filtering against the first batch of data and not searching subsequent batches

2. Premature "No Results": When no matches were found in the first batch, it incorrectly displayed "No iModels" even when matches existed in later batches

Problem Details

When we applied filtering via postProcessCallback (e.g., filtering by description or name of iModel):

• If matching iModels existed in both 1st batch of iModels and later batches, only the early matches would be shown
• If no matches existed in the first batch but did exist in later batches, we get "No iModels"

Solution

Added a useEffect to continue loading data when needed:

React.useEffect(() => {
  if (
    iModels.length < pageSize &&
    fetchMore &&
    fetchStatus !== DataStatus.Fetching
  ) {
    fetchMore();
  }
}, [iModels.length, pageSize, fetchMore, fetchStatus]);
