Move TelemetryProcessor (PointNewValue batching/dedup/broadcast) from feeder to
plc_platform_core. PlatformBuilder.build() now auto-wires telemetry processing and
reconnect task. PlatformContext.emit_event() handles connection management side effects
(connect/reconnect/disconnect/subscribe/unsubscribe) directly. Simplify PlatformEventSink
trait from 6 methods to single on_event(). Feeder's AppEvent now only contains business
events; FeederPlatformEventSink only handles UnitsChanged for control runtime.

- Move source/point/equipment/tag/page handlers from feeder to plc_platform_core
using State<PlatformContext>; feeder re-exports via handler modules
- Keep batch_set_point_value in feeder (requires app-specific write key auth)
- Add PlatformEvent enum and persist_and_broadcast() in core for platform event
persistence to DB + WebSocket broadcast
- Add PlatformContext::emit_event() that handles both sink notification and
async persistence in one call
- Add platform_routes<S>() in core for centralized route registration;
both feeder and ops merge it instead of duplicating route definitions
- Implement FromRef<AppState> for PlatformContext in both apps
- Add FeederPlatformEventSink adapter bridging core events to feeder's
EventManager + ControlRuntimeStore
- Add event namespace prefixes: platform.source.created, feeder.unit.fault_locked, etc.
- Register full platform CRUD routes in ops app
