Before this commit, the payment button was part of the checkout/manage
form widgets, which caused conflicts when other modules needed to
enable/disable the button depending on custom conditions.
After this commit, the payment button logic is extracted in a separate
widget that handles its enabling after checking if all conditions are
satisfied. Other modules can extend the widget and override
`isButtonReady` to add custom logic.
