feat(webui): Set up ANTLR tooling for future client-side SQL parsing; Move clp-s parser generation to codegen.yaml; Remove unused client package-lock.json.

[hoophalab]

Description

1. Add the ANTLR dependency in the webui client.
2. Use the grammar file from the 0.293 release of the Presto repository
   https://github.com/prestodb/presto/blob/release-0.293/presto-parser/src/main/antlr4/com/facebook/presto/sql/parser/SqlBase.g4

3. Include the generated parser files directly in the codebase similar to refactor(clp-s): Add ANTLR-generated parsers to codebase to eliminate need for code dependencies at build time. #925.
4. Add an example validate function for SQL input.

Checklist

Validation performed

validate detects incorrect sql queries.
clp-s-generate-parsers works the same as before.
webui-generate-parser generates the parser correctly.

Summary by CodeRabbit

• New Features

  • Introduced SQL syntax validation in the web UI with case-insensitive parsing and clear line/column error messages.

• Chores

  • Added a new runtime dependency to support the parser.
  • Centralized and automated parser code generation via shared tasks.
  • Updated CI workflow to use the new codegen task.
  • Excluded generated files from linting to reduce noise.
  • Updated notices to include third‑party attribution.
