fix: use assert instead of require in HTTP handlers

Replace require.NoError with assert.NoError inside HTTP handler
functions to fix testifylint go-require violations. Using require
in HTTP handlers can cause unpredictable test behavior since
t.FailNow() only exits the current goroutine (the handler), not
the main test goroutine.
