feat: support comma-separated AI_MODEL for quick multi-model setup (#870)

Users expected setting AI_MODEL to a comma-separated list to expose
multiple models in the picker, but the value was used verbatim as a
single model id, leaving the picker with only the "Server Default"
fallback.

Add a third-priority fallback in loadEnvServerModelsConfig: when
AI_MODELS_CONFIG and ai-models.json are both absent, AI_MODEL contains
a comma, and AI_PROVIDER is set to a known provider, synthesize an
equivalent ServerModelsConfig with the provider's models trimmed,
deduplicated, and the first marked as default.

Also makes getAIModel and getValidationModel pick the first comma-split
value when falling back to AI_MODEL, so requests started before the
client picker hydrates still resolve to a real model id.

Docs (en/cn/ja) and env.example updated; tests cover the new fallback
plus the no-comma / no-AI_PROVIDER negative cases.

Create an `ai-models.json` file in the project root (or set `AI_MODELS_CONFIG_PATH` to a custom location).
**Option 3: Comma-separated `AI_MODEL`** (quick setup, single provider)
If you only need multiple models from one provider, list them in `AI_MODEL` separated by commas. The first model is treated as the default.
```bash
AI_PROVIDER=doubao
AI_MODEL=doubao-seed-1-8-251215,doubao-seed-1-6-flash,doubao-seed-1-6-pro
```
This is shorthand for the equivalent `ai-models.json`. For multiple providers or custom `apiKeyEnv` / `baseUrlEnv`, use Option 1 or 2 instead.
### Example Configuration
