feat: prepare snowflake and cron service for snowflake data export [CM-945]

[mbani01]

This pull request introduces a new scheduled job to export data from Snowflake to S3 and significantly refactors the Snowflake client to support programmatic access token authentication in addition to key-pair authentication. It also updates dependencies to use the latest Snowflake SDK. The changes improve flexibility, security, and automation for Snowflake data exports.

Snowflake S3 Export Job:

• Added a new job (snowflakeS3Export.job.ts) that exports batches of data from Snowflake to S3 as Parquet files, supporting incremental exports based on the last run timestamp, and tracks progress using Redis.

Snowflake Client Refactor:

• Refactored the SnowflakeClient to support both programmatic access token and key-pair authentication, using a new configuration interface and dynamic connection options. [1] [2]
• Added a static fromToken method to SnowflakeClient for convenient instantiation using environment variables for token-based authentication.

Dependency Updates:

• Updated the snowflake-sdk dependency from version ^1.14.0 to ^2.3.3 to ensure compatibility with new features and authentication methods.
• Added @crowd/snowflake as a dependency to the cron service to enable use of the new client and job.

Note

Medium Risk
Touches data-export infrastructure and Snowflake authentication/connection setup; failures could affect scheduled exports or connectivity, though the changes are localized and additive.

Overview
Introduces a new cron-service job to export Snowflake query results to S3 (Parquet), intended to run incrementally and track progress/state between runs.

Refactors @crowd/snowflake’s SnowflakeClient to support either key-pair JWT auth or programmatic access token auth (new config union + fromToken() helper), and bumps snowflake-sdk to ^2.3.3. The cron service now depends on @crowd/snowflake and adds S3/Parquet-related dependencies needed for the export flow.
