q9: add table-driven httptest coverage for REST handlers

Add comprehensive table-driven tests in handlers_more_test.go covering all
previously un-tested handlers and middleware paths. Includes negative tests
(nil service, invalid IDs, missing bodies, service errors) and real-file
assertions for stream/download/thumbnail.

coverage: 58.8% -> 94.9%
