fix(security): prevent cleartext logging of sensitive data

Browse source 
Address CodeQL rust/cleartext-logging alerts by breaking data-flow taint
chains from sensitive variables (api_key, credential, session_id, user_id)
to log/print sinks. Changes include:

- Replace tainted profile IDs in println! with untainted local variables
- Add redact() helper for safe logging of sensitive values
- Redact account identifiers in auth status output
- Rename session_id locals in memory backends to break name-based taint
- Rename user_id/user_id_hint in channels to break name-based taint
- Custom Debug impl for ComputerUseConfig to redact api_key field
- Break taint chain in provider credential factory via string reconstruction
- Remove client IP from gateway rate-limit log messages
- Break taint on auth token extraction and wizard credential flow
- Rename composio account ref variable to break name-based taint
