fix(connections): send boolean activity params as true/false [PC-5201]

[dianagrecu-uipath]

Summary

• Integration Service activity parameters sent in the query string, the path, headers or as multipart form fields now serialize booleans as true/false instead of Python's True/False.
• Strings, numbers and request bodies are unchanged.
• Bumps uipath-platform to 0.2.35.

Why

_build_activity_request_spec converted every value with str(value), so a boolean tool argument went out as ?saveAsDraft=True. The IS connector hooks compare these values to the lowercase string, for example requestParams?.saveAsDraft == 'true' in the Gmail EmailReply / ForwardMailV2 and Outlook send-mail-v2 / ReplyToEmailV2 hooks. The check fails, so "Save as draft" is ignored and the email is sent. The same check is used for replyToAll, markAsRead, includeSubfolders and other flags.

Reported by a customer in UV-16521 (Gmail "Reply to Email" with "Save as draft" set as a static value). The .NET agent executor already sends lowercase values. Maestro hit the same issue in ENGCE-56530.

Testing

• Reproduced on alpha with the Outlook "Send Email" tool: the same request was delivered with saveAsDraft=True and saved as a draft with saveAsDraft=true.
• New unit tests cover boolean query, header, path and multipart values; they fail on main with 'True' == 'true'.

[Copilot]

🟢 Approval recommended

The implementation matches the stated behavior, preserves non-boolean values, and includes focused regression coverage.
