refactor(phase3-session-b3): extract create, transform, compress, convert into sub-routers
Extracted remaining 4 endpoint groups: - create.py: 7 endpoints (create, 3xtemplates, providers, estimate-cost, platform-specs) - transform.py: 4 endpoints (image-to-video, talking-avatar, estimate-cost, video serving) - compress.py: 5 endpoints (compress, batch, estimate, formats, presets) - convert.py: 4 endpoints (convert-format, batch, supported, recommendations) Legacy router is now empty (only imports + empty router definition). All 33 routes preserved. Package is fully modular.
