[cli] Add CLI version argument

[Haralishev77]

Summary

Simplify the CLI/runtime by removing the unused CARLA version configuration.

Changes

• Changed -v / --version to print OpenCDA v0.3.0 and exit.
• Deferred optional runtime imports so --version works without scenario dependencies installed.
• Removed carla_version from scenario managers, blueprint filtering, map helpers, scenario calls, and tests.
• Simplified blueprint selection to the current supported CARLA environment.
• Fixed forwarding of carla_timeout from CoScenarioManager to ScenarioManager.

Validation

• Simulation run
• Manual verification
