The UK BACS payment module now correctly depends on the UK localization module. This helps ensure the required UK banking functionality is installed automatically when needed, reducing setup issues for users.

### Steps to reproduce:
- Install the 'l10n_uk' module
- The module "l10n_uk_bacs" is not installed, but it should

### Solution:
Make the `l10n_uk_bacs` module dependent on `l10n_uk`.

When running `./odoo-bin --addons-path="addons/,../enterprise/" -u l10n_uk_bacs -d [db]` it detects the unmet dependency (`module l10n_uk_bacs: Unmet dependencies: l10n_uk`) and installs it. So I guess there is no need for an upgrade script.

The global dictionary containing the translations cannot be modified.

This fixes subscription behavior so only invoices tied to the current subscription are considered when checking for active draft invoices. It prevents unrelated contract invoices from affecting subscription payment and renewal tests, improving reliability without changing expected business workflows.
