Feature/controller evcs analog heatingelement reference target

[PunugupatiSaikumar]

Summary

Migrates three controllers from OpenemsComponent.updateReferenceFilter() to the Reference Target Plugin (@GenerateTargetsFromReferences).
This continues the same migration as the ESS controller PRs. The plugin resolves ${config.*_id} into the OSGi reference target before @Activate, so the runtime filter rewrite is no longer needed.

Bundles

1. Controller.Evcs

• @GenerateTargetsFromReferences("evcs")
• Reference: STATIC / GREEDY / MANDATORY with
  target = "(&(id=${config.evcs_id})(enabled=true))"
• Removed evcs_target() from Config / MyConfig
• Kept ConfigurationAdmin (cm) — still used to rewrite force-/default-charge power when hardware limits are exceeded
• Tests: JUnit 4 → Jupiter; DummyConfigurationAdmin kept because cm is still used

2. Controller.IO.Analog

• @GenerateTargetsFromReferences("analogOutput")
• Reference: STATIC / GREEDY / MANDATORY with
  target = "(&(id=${config.analogOutput_id})(enabled=true))"
• Removed analogOutput_target() from Config / MyConfig
• Removed cm — it was only used for updateReferenceFilter
• Optional timedata reference unchanged
• Tests: JUnit 4 → Jupiter; DummyConfigurationAdmin removed

3. Controller.IO.HeatingElement

• @GenerateTargetsFromReferences("meter")
• Optional meter (same pattern as Controller.IO.HeatPump.SgReady):
  cardinality = OPTIONAL, policyOption = GREEDY,
  target = "(&(id=${config.meter_id})(enabled=true))"
  (not STATIC, because meter_id defaults to "")
• Removed the old empty-id (false=true) / updateReferenceFilterRaw handling
• Removed meter_target() from Config / MyConfig
• Removed cm — it was only used for the meter filter
• Tests: removed unused DummyConfigurationAdmin wiring only (left on JUnit 4 to keep the diff small)

Thank you for proceeding. I am awaiting the moment when we can remove updateReferenceFilter() 🚀 (not sure if this will actually be possible, though)
