We are upgrading our Stacks Mainnet API infrastructure to stacks-blockchain-api-v9.0.2.

This patch fixes a critical issue where transactions reported as `problematic_skipped` by the Stacks node caused API ingestion to stall.
The release also improves error reporting from the API to the Stacks node during block ingestion failures and includes security-related dependency updates.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
/v3/tx/events — Fixed a bug where asset identifiers containing digits caused 500 errors; these requests will now succeed.
