Currently when users change the rounding unit filter in the Journal Report, the Global Tax Summary values remain in the old format instead of updating to reflect the new rounding setting. This creates inconsistency where main report values update correctly but tax summary values stay unchanged.

Cause:
- The issue occurs because `_format_column_values` method in `account_report.py` wasn't handling the special tax summary data structures (`tax_report_lines` and `tax_grid_summary_lines`) that store pre-formatted values. These structures need to be reformatted when rounding unit changes, but the formatting logic only covered standard report columns.

Fix Applied:
- Updated frontend (`filters.js`) to call `format_column_values_from_client` via
  `dispatch_report_action` instead of calling `format_column_values` directly.
  (this enables proper routing through the custom handler system)
- Added `format_column_values_from_client` override in `JournalReportCustomHandler`
  that intercepts the formatting call and applies special handling for tax summary
  lines by adding logic to reformat `tax_report_lines` and `tax_grid_summary_lines`
  monetary fields using their `_no_format` counterparts.
- The custom handler then delegates to the base method via
  `report.format_column_values_from_client()` to format standard columns.
- Also added missing `_no_format` fields in `account_journal_report.py` for
  `base_amount` and `tax_amount` to enable proper reformatting.
