fix: remove electrical component control mode (#359)

It was determined that we do not want to make this part of the common
API definition for `ElectricalComponent`

 - Added new message definitions for streaming events (Deleted, Created, Updated)
 - Remove unnecessary gap in numbering in the `ElectricalComponentCategory` enum.
 - Renumber variants in the `Metric` enum to remove unnecessary gaps.
-- Added a new enum `ElectricalComponentControlMode` to define control modes for electrical components.
 - Renamed `metric_sample.proto` to `metrics.proto` to better reflect its content.
 - Renamed electrical component category `COMPONENT_CATEGORY_GRID` to `ELECTRICAL_COMPONENT_CATEGORY_GRID_CONNECTION_POINT` to clarify its meaning. Note that the change in the enum change is a part of a larger refactoring of the electrical component category enum.
 - The oneof variant `ComponentCategoryMetadataVariant.metadata.grid` has been renamed to `ElectricalComponentCategorySpecificInfo.info.grid_connection_point` to better reflect its purpose.

-// `ElectricalComponentControlMode` explicitly defines whether an electrical
-// component is intended to be active (enabled) or inactive (disabled). This
-// intentional setting directly determines component availability to downstream
-// agents, applications, and services.
-//
-// !!! note "Control Mode & Component Availability"
-//     The Control Mode explicitly represents the user's or automation's
-//     intention to make the component either ACTIVE or INACTIVE. This directly
-//     impacts availability:
-//     - ACTIVE indicates the component is intended to be available and usable
-//       by downstream agents and services.
-//     - INACTIVE indicates the component is intended to be unavailable for use
-//       by downstream agents and services.
-//
-// !!! note "Relationship with Operational State"
-//     Control Mode explicitly represents intention, distinct from the
-//     component's actual internal Operational State.
-//     Operational State is independently reported by the component hardware
-//     (e.g., READY, CHARGING, DISCHARGING, ERROR).
-//
-// !!! caution "Immediate Operational Impact"
-//     Changing the Control Mode of an electrical component (e.g., via the
-//     Microgrid API) takes immediate effect on its availability to downstream
-//     agents and services. Setting a component to `INACTIVE` can thus instantly
-//     interrupt ongoing operations or cause service disruptions. Setting a
-//     component to `ACTIVE` may immediately connect it with other components,
-//     potentially causing electrical damage. Therefore, ensure changes are
-//     coordinated or planned appropriately to avoid unintended impact and/or
-//     damages.
-//
-// !!! example "Control Mode Change Impact"
-//     If a battery component's Control Mode is switched from `ACTIVE` to
-//     `INACTIVE`, it immediately becomes unavailable to downstream
-//     services and agents, potentially disrupting scheduled
-//     charging/discharging cycles.
