fix(playback): honor source color range fallback

[Quick104]

Summary

• decode color_range from catalog metadata and the additive playback-v3 source descriptor
• carry the range through phone and TV playback media specs
• map FFmpeg tv to Media3 limited range and pc to full range only when extractor color range is unspecified
• compose the fallback with existing HLG and Dolby Vision corrections instead of replacing them

Why

Silo preserves direct-play bytes, but Media3 can receive an unspecified container range. The server-probed FFmpeg value supplies a safe fallback while explicit extractor metadata remains authoritative.

Testing

• focused shared and android-shared unit tests for catalog/v3 serialization, session conversion, and limited/full/conflict/unknown mappings
• :androidApp:compileDebugKotlinAndroid
• :androidTvApp:compileDebugKotlinAndroid
• autoreview clean

Coordination

Depends on Silo-Server/silo-server#447.

Part of Silo-Server/silo-server#446

AI use

Implemented with OpenAI Codex. The generated patch was reviewed, focused tests and both client compiles were run, and review findings were addressed before publication.
