The SEPA payment and payroll SEPA features have been consolidated into their main modules, reducing the number of separate add-ons to maintain. This should make future updates easier while keeping SEPA payment capabilities available in the standard modules.

In an effort to simplify the codebase and enhance maintainability, this commit merges account_sepa_pain_001_001_09 into account_sepa and hr_payroll_account_sepa_09 into hr_payroll_account_sepa.

Odoo removed an older internal messaging mechanism and updated affected areas to use newer shared communication paths. This reduces outdated code and helps keep features like push notifications and barcode workflows easier to maintain without changing expected business behavior.

This commit removes the legacy global bus (core bus) and the places where it was used.
The main users of this bus were the public widgets, a shared bus has been added on PublicWidget.
Some of the uses were dead code and has been removed.
