feat(spatius): update sdk to 1.1.1 and forward session options

[3DRX]

Summary

Upgrade spatius[opus] from 1.0.4 to 1.1.1 and expose params.extra_params
so callers can pass server session options such as
{"server_post_process": "false"} to the SDK. Copy these options during
configuration normalization and session creation to isolate caller state.
The manifest exposes params.extra_params as an object with an empty default.

Automatic region selection now appears in connection-success logs and the
existing vendor_metadata.region field using the SDK session's resolved region.
The requested configuration stays intact, and disconnect clears session-specific
reporting. Explicitly configured regions continue to work.

The SDK upgrade includes automatic region selection and caching, shared TLS setup,
initialization telemetry, and separate 10-second session-token request and
WebSocket server-confirmation timeouts. Preserve the extension's 24 kHz Ogg Opus
default, explicit 30-minute token expiry, Agora egress, and TEN lifecycle. Optional
prewarming and token prefetching are not enabled.

Set the extension version to 0.2.5.

Validation

Validated with Python 3.10.12 and Spatius 1.1.1 in a disposable container using
ghcr.io/ten-framework/ten_agent_build:0.7.14:

• task test-extension EXTENSION=agents/ten_packages/extension/spatius_avatar_python:
  18 passed, including 14 new parameterized session regression cases.
• Tests use the real SDK constructor/configuration types with mocked network
  operations. Coverage includes automatic/pinned regions, Agora configuration,
  Opus/PCM and expiry settings, defensive copying, resolved-region reporting and
  cleanup, audio/EOF/interruption/shutdown, and startup error propagation without
  launching the audio processing task.
• task check: passed, 1,432 Python files unchanged by Black.
• task lint-extension EXTENSION=spatius_avatar_python: passed, 10.00/10.
• git diff --check, Python syntax, JSON manifests, version and dependency
  consistency checks: passed.
• Full task lint: failed on unrelated extensions, with no Spatius
  diagnostics. The environment lacks other vendors' dependencies, and
  smallest_tts_python references a missing ten_ai_base.utils.redact_headers
  member. The full repository lint gate is not claimed as passing.

Live Spatius/Agora playback was not exercised. A supplemental pip check reports
the development image's existing pygobject dependency on missing pycairo.
