The auth dependency raises NotAuthenticatedError (not HTTPException),
and the exception handler returns a 302 redirect. Updated the unit test
to expect NotAuthenticatedError, and all route auth tests to accept 302
alongside 401/303.
Pre-fill the reps and weight inputs with progression engine suggestions
so users can log sets without manually retyping values each time.
Suggestions flow through the template chain on initial page load and
on all HTMX partial responses (log, edit, delete).
