This PR adds core Oracle support to the Analytics Toolbox, implementing the foundational infrastructure for deploying SQL functions to Oracle Autonomous Database.

Summary of Changes

Core Oracle Implementation:

• Build system and deployment scripts for Oracle
• Schema management (create/drop schema scripts)
• Wallet-based authentication for Oracle Autonomous Database
• SQL UDF deployment infrastructure
• Testing framework for Oracle functions

Standardization:

• Uses ORA_* prefix for all environment variables (consistent with BQ_, SF_, RS_ pattern)
• Implements ORA_SCHEMA for explicit schema naming (Oracle schemas are tied to users)
• Template variable system with @@ORA_SCHEMA@@, @@ORA_VERSION_FUNCTION@@, @@ORA_PACKAGE_VERSION@@

Build System:

• build_modules.js: Dependency resolution and module ordering
• GRANT_ACCESS.sql: Helper procedure for permission management (always included)
• INTERNAL_DROP_FUNCTIONS.sql: Clean function removal
• VERSION.sql: Version tracking function

Deployment Infrastructure:

• run_script.py: SQL script execution with wallet authentication
• create_schema.py: Schema-only user creation with NO AUTHENTICATION
• drop_schema.py: Schema cleanup and removal

CI/CD:

• GitHub Actions workflow for Oracle (test, deploy-internal jobs)
• Dynamic schema naming for CI environments (CI_{sha}_{run_id})
• Automated testing on Oracle Autonomous Database

Documentation:

• Environment variable configuration guide
• Wallet authentication setup instructions
• Schema management best practices
• Cross-schema access patterns
