Payroll salary attachments now use the existing payslip input type setup instead of a separate attachment type configuration. This reduces duplicate setup, keeps payroll rules more consistent, and simplifies maintenance for companies using salary deductions or attachments.

The bank synchronization flow now imports missing transactions made in a currency different from the account currency without losing the original payment currency information. This helps businesses reconcile multi-currency bank activity more accurately and reduces manual corrections.

Some banks allow customers to make payments in multiple currencies on their account. This commit will support importing transactions that are in another currency than the account currency through 'Find Missing Transactions' wizard without losing the information that they're paid in another currency.

The addenda selection for Mexican electronic invoicing is now shown in the Accounting area of a contact instead of Sales. This makes the setting easier to find where users expect invoice-related configuration to be.

Users (both technical and non-technical) expect to see the configuration for addendas under Accounting as they are more related to electronic invoicing than sale orders

Activity views and related extensions are now loaded only when needed. This can improve initial loading performance across affected apps while keeping the same user-facing functionality.

We make the activity view and its extensions to be lazy loaded.

The report editor now records user edits as clearer, more focused change instructions instead of saving a large replacement of the whole report structure. This should make future upgrades and maintenance easier for partners and developers while preserving the same editing workflow for users.

The US NACHA payment module was updated to meet current automated code quality checks. This reduces friction for future fixes and maintenance without changing business functionality.

"".format() is no longer allowed. This is enforced by the check_style_ruff step in runbot. Every bugfix touching these lines requires an exception from the runbot team. This converts every string formatting operation in l10n_us_payment_nacha to an f-string. Every bugfix will now conflict, but at least we won't have to bother the runbot team.

This was done automatically with flynt [1], which as far as I can tell did a perfect job.

Fixing that makes other errors pop up (e.g. FURB113 to replace multiple append() calls with a single extend()). This commit fixes those as well. The remaining ones in the module are easy and were done as well (removing # coding and super() arguments).
