 """Strip a language string; treat blanks as unset; reject unsafe values.

 The language string is interpolated into LLM system prompts (see
 ``_SYSTEM_TEMPLATE`` in ``openkb/agent/compiler.py`` and the query agent's
 instructions), so values with newlines or excessive length would let an
 external caller smuggle instructions into the prompt. Capping at
 ``_LANGUAGE_MAX_LEN`` and rejecting control characters is enough to close
 that vector while still allowing common forms ("en", "ko", "Korean",
 "Simplified Chinese").

 Returns the cleaned string, or ``None`` if the input was missing or blank
 after stripping. Raises ``click.BadParameter`` on unsafe input.
