Add transform processor debugger, multiple config support, and major refactoring

[edmocosta]

• [experimental] Added support for debugging transform processors configs
• Added support to multiple configurations blocks, including support to YAML component type and IDs keys, e.g transform/rename_fields".
• The result view and examples of config and payload are now WASM-driven. It also includes additional executor's metadata.
• Changed the transform processor examples to use the new context inferred syntax.
• Added WASM panic handler, showing the error also on the UI (in addition to the console).
• Changed the config panel to not render the code mirror editors on every panel activation.
• Adding several missing unit tests.
• [chore] Split PData consumers from executors logic.
• [chore] Renamed CI command references to processors as executors.
• [chore] Bump default dependencies versions.

Pull request overview

This PR introduces experimental debugger support for transform processor configurations, adds support for multiple configuration blocks with YAML component type/ID keys, and performs major refactoring to separate consumer logic from executor implementation while improving test coverage.

Key changes:

• Debugger Implementation: Added step-by-step debugging capabilities for transform processor configurations with UI controls and breakpoint support
• Multiple Configuration Support: Implemented parsing and execution of multiple configuration blocks (e.g., transform/rename_fields) in a single YAML file
• Architecture Refactoring: Split PData consumers from executor logic, introducing new Consumer, Observable, and Debugger interfaces with improved separation of concerns
