Use orjson for request serialization to preserve unicode

[frenck]

Proposed Changes

Replace aiohttp's built-in json= parameter with orjson.dumps() for outgoing requests. aiohttp uses stdlib json.dumps which escapes non-ASCII characters to \uXXXX sequences, causing segment names with characters like éçà to be stored as escape sequences on the device. orjson (already a dependency) serializes to proper UTF-8 by default.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.
