This commit introduces the "useWowlService" hook. This hook allows Owl components that use the legacy env (not the one of the webclient for instance, typically called the "wowl" env) to access services from the wowl env. Its API is the same as the classical "useService" hook. closes odoo/odoo#85769 Signed-off-by: Géry Debongnie <ged@odoo.com>
