   fix(dashboard): load charts correctly
   -->
   
   ### SUMMARY
   Bug: When using a Time Column native filter on a dashboard using legacy 
charts like Country Map, the user column selection was being ignored and it was 
always filtering using the dataset default temporal column. 
   
   Root Cause: The issue was in the backend's merge_extra_form_data function, 
which was receiving the user selected column but was not updating the subject 
in the TEMPORAL_RANGE adhoc filter.
   
   Fix:  Change the merge_extra_form_data fuction to update the adhoc filter's 
subject of TEMPORAL_RANGE when granularity_sqla is provided via extra_form_data.

   ### TESTING INSTRUCTIONS
   #### 1. Create and load the test table (or any table with multiple temporal 
columns), e.g. country_map_us_states_test with:
   - iso_3166_2_code (e.g. US-CA, US-TX)
   - metric_value (numeric)
   - Three temporal columns:
   -- event_date (DATE)
   -- created_at (TIMESTAMP)
   -- updated_at (TIMESTAMP)
   #### 2. Create a dataset from country_map_us_states_test and mark all three 
temporal columns (event_date, created_at, updated_at) as temporal.
   #### 3. Create a new chart using:
   - Chart type: Country Map
   - Country: United States
   - ISO 3166-2 Codes: iso_3166_2_code
   - Metric: SUM(metric_value)
   #### 4. Save the chart.
   
   #### 5. Add this Country Map chart to a dashboard.
   #### 6. Add a native filter of type Time Column to the dashboard.
   In the filter configuration:
   - Choose Time Column = created_at (or any non-default temporal column).
   - Set a time range, e.g. 2024-01-01 → 2024-03-01.
   - Apply the filter and open … → View query on the Country Map chart.
   
   #### Expected results
   The time range filter is applied over the column that the “Time Column” 
filter says.
