refactor(@embark/plugins/profiler): re-enable embark-profiler plugin

Hook `embark-profiler` into the engine's contracts group.

Adjust `request` signatures to match v5 usage.

Ensure gas numbers are formatted consistently in the ascii table.

Display non-json output in cockpit's console as monospace/pre to preserve
profiler table formatting.
