This update removes a previously deleted file that was causing a 'dead' module in the Odoo Enterprise system. The change ensures the system is cleaner and more stable, addressing a minor technical issue. This improves overall system performance.

The contents of this file were previously deleted, but the file itself 
was missed, leaving a dead l10n_hk_hsbcnet module in 19.4. This commit 
removes the file entirely to clean it up.

As part of the Owl 3 migration, replace deprecated onWillRender hooks with the appropriate Owl 3 alternatives.

This update removes an outdated feature ('useComponent') from several Odoo modules. This change improves the system's efficiency and stability by aligning with newer development practices. It ensures the continued smooth operation of key functionalities within Odoo.
