(fix) Improve error handling and output

[HarK-github]

Fixes #758
This PR addresses minor hardcoded message discrepancies, improves error messaging specificity for config parsing failures, and refactors argument passing in fabric-docker.sh to prevent parameter truncation.

Changes:

Validation & Config:

• Updated src/commands/validate/index.ts and src/config.ts to use a single source of truth (minFabricVersionRaft) for Raft consensus error messages instead of relying on a raw function reference layout.

Fablo Config Parser:

• Enhanced src/utils/parseFabloConfig.ts to surface underlying error messages from both the JSON and YAML parser attempts. Added a corresponding unit test in parseFabloConfig.test.ts.

Templates & Scripts:

• Refactored src/setup-docker/templates/fabric-docker.sh to use ${@:3} and ${@:2} syntax instead of strict positional assignments ($3 $4 $5...). This safely relays all extra arguments downstream to chaincode and channel commands.
• Fixed a typo in chaincode-scripts.sh where a validation error for a chaincode invoke failure was mistakenly printing "Expected X parameters for chaincode list".

Tests:

• New unit test passes verifying detailed parser error throwing.
• Verified that dynamic arguments translate seamlessly to docker runtime routines.
