This update adds broader automated JavaScript checks across several Odoo apps and corrects issues such as undeclared variables. It helps reduce future errors during development without changing day-to-day user workflows.

[IMP] *: configuration of ESLint for specific files

This commit will add the needed ESLint configurations on the JS files.
These configurations are added if the JS file uses a different
environment (serviceworker, node, etc) or if it uses a specific global
(google, ace, etc).

[FIX] *: undeclared variables and restricted globals

This pull request reorganizes several internal web interface files and updates related tests and setup references across multiple Odoo apps. The changes help keep the platform easier to maintain while preserving existing business workflows such as accounting reports, documents, barcode operations, subscriptions, planning, timesheets, and signing.
