refactor: LLM client for calling supplier LLM APIs (not server)

Replaces wrong-direction llm_api.py (which served OpenAI endpoints)
with llm_client.py -- a client that calls supplier LLM APIs.

New module: llm_client.py
  - llm_chat(messages, model, temperature, ...) -> OpenAI response dict
  - llm_chat_stream(messages, ...) -> async generator of SSE chunks
  - llm_simple(prompt, system) -> plain text response
  - llm_list_models() -> list available models from provider
  - llm_get_config() -> show current config (key masked)
  - Supports provider presets: openai, dashscope, deepseek, siliconflow
  - Retry with exponential backoff (3 attempts)
  - 429 rate limit handling with Retry-After
  - Structured logging via appPublic.log

Model changes (harnessed_agent_config):
  - Add llm_provider (preset name: dashscope/openai/deepseek/siliconflow)
  - Add top_p field
  - llm_service_url defaults to DashScope compatible endpoint

Other:
  - Remove wrong-direction /v1/ endpoints
  - Fix pyproject.toml deps: only sqlor + bricks_for_python
  - Update init/data.json seed data with LLM config fields
  - Update CRUD view with llm_provider dropdown
