fix(voice): send OpenAI Realtime tool schemas the API accepts

OpenAI Realtime now answers 400 invalid_function_parameters for a whole
session whose tool schema uses Unicode property classes, as resolve_area's
area-id pattern does, so voice never connects ("Failed to create Realtime
token"). The session sends its tools through chatSchema, the filter typed
chat adopted in #1616, which leaves out only \p{…} patterns; area ids are
still checked against the action's own contract before the tool runs.

Fixes #1618
