[IMP] l10n_ro: add missing tax mappings for new VAT rates

Coresaas-18.3l10n_roMedium

This update ensures Odoo correctly handles the new 11% and 21% VAT rates introduced in Romania. By adding missing tax mappings, the system now accurately reflects the latest Romanian VAT regulations and ensures proper fiscal position calculations.

Original PR description

The new 11% and 21% taxes introduced with the updated Romanian VAT law were added with this commit https://github.com/odoo/odoo/commit/2026212d0f7ffc217be3c6a2ff2abe5288c18afb , but some tax mappings were missing.

This commit completes the setup by adding the required tax mappings, ensuring the new rates work correctly with fiscal positions.

[IMP] account_reports: batch 'domain' engine when possible

PR #105029

Enterprisesaas-18.3accountMedium

This update optimizes how Odoo generates reports by grouping related database queries. Previously, each report filter required a separate SQL query, which was slow. Now, multiple filters targeting the same data are combined into a single query, significantly speeding up report generation times – specifically, the Generic Balance Sheet now runs in 36 seconds instead of 1 minute 35 seconds.

Original PR description

Before this commit, the 'domain' engine was never batched: one expression to evaluate caused one SQL query to be run just for it. With this commit, we group domains that could be evaluated together.

Essentially, when we have domains targetting the same many2one field of account.move.line (typically account_id, with conditions like 'account_id.code' or 'account_id.account_type'), we run only one SQL query for all of them, targetting all the move lines according to the report filters. Then, we iterate on its result for each domain to evaluate. When iterating over the results, we filter the ones we keep by searching separately on each traversing model (in our example, account.account), to isolate the ones that are actually targetted by each expression.

Tested on our prod. With this, opening the Generic Balance Sheet goes from 1min 35s to 36s.
