refactor: node breaker updates

[nicow-elia]

Moves the SwitchUpdateSchema into a new module NodeBreakerUpdate which unifies pst setpoint changes and switch updates into one dataclass. Also extends the orao json export with the new pst setpoints.

Next up (in a separate PR) I'd include this into the postprocess runners so that we are sure we are validating the same thing.

Pull request overview

This PR refactors “switch updates” into a unified low-level node-breaker update model that groups both switch state changes and PST tap setpoint changes, and extends ORAO JSON export to include PST actions.

Changes:

• Introduces NodeBreakerUpdate (+ PSTUpdateSchema) and migrates SwitchUpdateSchema into the new module.
• Updates DC solver export to produce NodeBreakerUpdate via get_node_breaker_updates_from_action_set(...) (including PST setpoints).
• Updates AC summary export/tests to serialize both switch and PST actions into ORAO JSON.
