Steps:
- Install account app.
- Create a branch company under the main company.
- Create a tax for the branch company.
- Add a main company tax on a product.
- Switch to branch company.

Issue:
- Tax string is not displaying on the product form even though its setting tax from parent company on invoice line and SO line so its displaying wrong sale price on product form.

Cause:
- After [PR] taxes are only consider from current company even though company is branch company but in [17.0 PR] we share taxed and other accounting related data b/w main and branch company so if branch does not it's specific tax applied on product then it should take tax from its parent company.

Fix:
- Compute tax_string in product the way we compute tax on invoice line, SOL etc using `_filter_taxes_by_company` method this way it'll give proper tax which will be applied on related documents.

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.
