Clearer procedure IDs in docs and SDK examples

Code examples now use an obviously-fake placeholder procedure ID instead of a name or a real-looking UUID, so a copy-pasted snippet can't accidentally target a real procedure and clearly reads as a value to replace.

• Replaced name-style (FVT1) and a real-looking UUID with xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx across the OpenHTF and SDK docs and the V1 API example.
• Clarified that procedure_id is the dashboard procedure UUID (a legacy external identifier only resolves if one was set).
• Updated the OpenHTF client docstrings and released python client 2.13.2.
