[feedback] Add FeedbacActuatorBase, migrate FeedbackCover (cover/valve refactor 6/7)

[exciton]

Mirrors the time_based and endstop refactors (PRs 2/5 and 3/5): extracts the feedback-cover control logic into a reusable FeedbackActuatorBase that drives any actuator entity through the IActuator interface, and moves the cover platform into a subpackage.

New layout:
feedback/init.py — FeedbackActuatorBase, FEEDBACK_ACTUATOR_SCHEMA,
apply_feedback_actuator_config helpers
feedback/feedback_actuator.h — shared base class (Component + IActuator*)
feedback/feedback_actuator.cpp — shared loop / control / sensor handling
feedback/cover/init.py — thin cover platform, AUTO_LOAD parent
feedback/cover/feedback_cover.h — FeedbackCover : FeedbackActuatorBase, Cover
feedback/cover/feedback_cover.cpp — get_traits + dump_config

No user-visible behaviour change. Existing YAML configurations continue to work unchanged.
