Odoo Enterprise was updated to use a newer internal way of identifying selected companies across many modules. This keeps multi-company behavior consistent with the main platform update and reduces future maintenance risk, with no expected direct change for end users.

This commit adapts the current code to use the new `companies`
evaluation context key, introduced in [1].

Note that, this commit is the output of the script that migrates the
code automatically.

This change updates internal wording for a search-related option used across several Odoo apps. It helps keep the codebase aligned with the main platform change, with no expected impact on day-to-day users.
