feat: add chart_type argument to refresh command (Task 3.1)

- Add --chart-type argument with choices: directory, indication, all
- Update insert_pathway_records to include chart_type column
- Update refresh_pathways to process multiple chart types
- Update logging to show chart type counts
- Indication chart processing deferred to Task 3.2 (GP diagnosis integration)

 ### 3.1 Update Refresh Command for Dual Chart Types
-- [ ] Modify `cli/refresh_pathways.py`:
+- [x] Modify `cli/refresh_pathways.py`:
   - Process both "directory" and "indication" chart types
   - For each of 6 date filters: generate 2 chart datasets
   - Total: 12 pathway datasets (6 dates × 2 chart types)
-- [ ] Add `--chart-type` argument: "all" (default), "directory", "indication"
+- [x] Add `--chart-type` argument: "all" (default), "directory", "indication"
-- [ ] Update progress logging to show both chart types
+- [x] Update progress logging to show both chart types
-- [ ] Verify: Dry run shows both chart types being processed
+- [ ] Verify: Dry run shows both chart types being processed (requires Task 3.2 for full indication support)
