Subject: [PATCH 3/4] fix(integrations): address RB2B PR review

- email_to_activity now has its own plaintext Email field (canonicalParamId) instead of sharing the Email-or-MD5 input, since it does not accept MD5 hashes
- RB2BIcon uses useId() for its clipPath id instead of a hardcoded id, matching the convention used by other icons

Subject: [PATCH 4/4] fix(integrations): map RB2B email_to_activity input via
 params, not canonicalParamId

The canonical-pair validation test requires canonical members to share the same
condition. Replace the cross-operation canonicalParamId reuse with two distinct
subblock ids (email for HEM ops, emailAddress for email_to_activity) and a small
tools.config.params remap to the email tool param.
