Add AI provider abstraction and asset storage (tasks #33, #34)

AiProviderDriver: one generic interface (generate(prompt, options) -> AiGenerationResult) rather than per-capability interfaces, since text (OpenAI chat completions), image (StabilityAI stable-image), and speech (ElevenLabs TTS) generation all reduce to prompt-in/content-out. Drivers throw AiGenerationException on failure; AiProviderManager resolves the right driver from an AiProvider record's `provider` column and guards on is_active. Real request/response shapes per each provider's API, verified with Http::fake() — no live API keys available yet to smoke test against the real services. AssetStorage: stores generated content under video-projects/{id}/{type}/v{n}.{ext}, versioned per (project, type[, step]) slot so retries don't clobber earlier output, plus contents/url/delete and pruneOldVersions for cleanup.
