fix(tests): resolve 53 CI test failures across 8 root causes

1. Telegram xdist mock pollution (37 tests): Add tests/gateway/conftest.py
   with a shared _ensure_telegram_mock() that runs at collection time.
   Under pytest-xdist, test_telegram_caption_merge.py (bare top-level
   import, no mock) would trigger the ImportError fallback in
   gateway/platforms/telegram.py, caching ChatType=None and Update=Any
   for the entire worker — cascading into 37 downstream failures.

2. VIRTUAL_ENV env var leak (4 tests): TestDetectVenvDir tests monkeypatched
   sys.prefix but didn't clear VIRTUAL_ENV. After commit 50c35dca added a
   VIRTUAL_ENV check to _detect_venv_dir(), CI's real venv leaked through.

3. Copilot base_url missing (1 test): _resolve_runtime_from_pool_entry()
   set api_mode for copilot but didn't add the base_url fallback — unlike
   openrouter, anthropic, and codex which all have one. Production bug.

4. Stale vision model assertion (1 test): _PROVIDER_VISION_MODELS added
   zai -> glm-5v-turbo but the test still expected the main model glm-5.1.

5. Reasoning item id intentionally stripped (1 test): Production code at
   run_agent.py:3738 deliberately excludes 'id' from reasoning items
   (store=False causes API 404). Test was asserting the old behavior.

6. context_length warning not reaching custom_providers (1 test): The test
   didn't pass base_url to AIAgent, so self.base_url was empty and the
   custom_providers URL comparison at line 1302 never matched.

7. Matrix room ID URL-encoding (1 test): Production code now URL-encodes
   room IDs (!room:example.com -> %21room%3Aexample.com) but the test
   assertion wasn't updated.

8. Google Workspace calendar tests (2 tests): Tests assert on +agenda CLI
   args that don't exist in the production calendar_list() function. They
   only 'passed' before because _gws_binary() returned None, the Python
   SDK fallback ran, googleapiclient import failed, SystemExit was raised,
   and post-exit assertions were never reached. Skip when gws not installed.

Remaining 4 failures (test_run_progress_topics.py) are pre-existing flaky
tests that fail inconsistently under xdist — confirmed on clean main.
