fix: adapt TemplateResponse calls to Starlette 1.0 new-style API

Starlette 1.0.0 changed TemplateResponse signature from
(name, context_dict) to (request, name, context=dict).

- Update base.py wrapper to convert old-style calls to new-style
- Update main.py error handler TemplateResponse calls
- Update local_auth.py, billing.py, auth.py, share.py calls
- Update test mocks for new calling convention
