Fix Starlette TemplateResponse deprecation in web UI routes

[iamh2o]

Summary

tests/test_web_server.py still emits Starlette TemplateResponse(...) deprecation warnings after the FastAPI lifecycle on_event migration.

The current warning is:

The name is not the first parameter anymore. The first parameter should be the Request instance.
Replace TemplateResponse(name, {"request": request}) by TemplateResponse(request, name).

Repro

From the repo root:

source ./zday_activate
pytest -q -W "error:.*on_event.*:DeprecationWarning" tests/test_web_server.py

That run now passes the on_event lifecycle check, but still reports Starlette TemplateResponse deprecations from the UI router.

Affected code

Current request-old-signature call sites are in zebra_day/web/routers/ui.py, including:

• zebra_day/web/routers/ui.py:209
• zebra_day/web/routers/ui.py:231
• zebra_day/web/routers/ui.py:341
• zebra_day/web/routers/ui.py:422
• zebra_day/web/routers/ui.py:453
• zebra_day/web/routers/ui.py:474
• zebra_day/web/routers/ui.py:522
• zebra_day/web/routers/ui.py:599
• zebra_day/web/routers/ui.py:619
• zebra_day/web/routers/ui.py:640
• zebra_day/web/routers/ui.py:686
• zebra_day/web/routers/ui.py:703
• zebra_day/web/routers/ui.py:916
• zebra_day/web/routers/ui.py:960

Expected fix

Update the Zebra Day template responses to the current Starlette/FastAPI request-first signature so these warnings go away on current dependencies.

Acceptance

• tests/test_web_server.py passes without Starlette TemplateResponse deprecation warnings.
• Zebra Day remains compatible with the current FastAPI/Starlette stack.
