This update streamlines the creation of guided tours within Odoo by removing a complex waiting mechanism. The change simplifies the tour API, making it easier for developers to create and manage tours. This improves overall system efficiency and consistency.

Before this commit, the `wait_for` key was used in tours to allow waiting
for a promise to resolve before starting the tour.

This commit removes all usages of `wait_for` in order to completely
eliminate it and simplify the tour API.

Since the tour engine already waits for a trigger and then executes the
action for each step, the same behavior can be achieved by defining an
initial step with a generic trigger (e.g., `body`) and an async `run`
function that awaits the promise.

This approach removes the need for a dedicated `wait_for` mechanism while
keeping the same flexibility and improving API consistency.

This change prepares Odoo for the upcoming OWL3 migration by replacing an outdated reporting directive, 't-esc', with the newer 't-out'. This ensures compatibility with the new system and avoids potential issues during the migration process. The update includes automated script execution and manual adjustments across multiple Odoo modules.

In OWL 3 the directive `t-esc` does not exist anymore.

In this PR to prepare for the OWL migration, we replace all `t-esc` directives by `t-out`.

This update simplifies the calculation of long-term sick leave in the Odoo Enterprise system for Belgium. Previously, sick time was automatically converted to unpaid after 30 days. Now, validating a sick leave request directly splits the time off into paid and unpaid portions according to Belgian legal regulations, ensuring accurate payroll processing.

This update prepares our appointment templates for a future upgrade (OWL3) that requires a specific syntax for referencing component variables. The team has automatically updated several appointment-related templates to include the necessary `.this` syntax, ensuring continued functionality after the OWL3 update. This is a proactive step to avoid potential disruptions.

In preparation for OWL3, where template variables will need to use `.this` to target component variables, we add `.this` to template variables that are targetting the component.

This update prepares Odoo for OWL3 by modifying template variables within the 'approvals' module. Specifically, the code adds `.this` to variable references, ensuring they correctly target component elements as required by the new OWL3 standard. This ensures continued functionality and compatibility with future updates.
