fix: update TemplateResponse calls to new Starlette signature

Starlette changed TemplateResponse from TemplateResponse(name, context)
to TemplateResponse(request, name, context). The old calling convention
passed a dict as the 'name' parameter, which Jinja2 tried to use as a
cache key inside a tuple, causing TypeError: unhashable type: 'dict'.

Updated all old-style calls in routes/tools.py and routes/calm.py to
use the new positional-request-first signature and removed redundant
"request" key from context dicts (Starlette adds it automatically).

Fixes #1114
