feat(console): dual-protocol provider presets + fix sub-path model discovery

Console — provider presets inside the model editor:

- Preset chips for five coding-plan providers (Zhipu GLM / Kimi / DeepSeek /
  Volcengine Ark / MiniMax) rendered at the top of the add/edit model dialog
- All five providers expose both an Anthropic-protocol and an
  OpenAI-protocol endpoint; a click fills the endpoint matching the current
  model type, and switching the type automatically swaps to the same
  provider's other endpoint (no stale URL/protocol mismatches)
- Switching to a different provider clears the API key; switching protocols
  within the same provider keeps it
- Fills base URL (full-request-URL form for irregular paths), request
  protocol, claude-cli custom headers for Anthropic endpoints, token limits,
  remark, and the default model id + display name; known preset model ids
  merge into the model-name combobox

Server — model discovery for sub-path endpoints:

- model_discovery_url previously replaced the whole path with /v1/models,
  which strips the /api/anthropic, /coding, /api/paas/v4 style prefixes every
  coding-plan provider uses, so discovery always 404'd for them. It now
  appends to the existing path and normalizes endpoint/version suffixes
  (/chat/completions, /responses, /messages, /v1, /v3, /v4)
- Verified live against Zhipu (10 models) and Kimi (4 models) coding plans;
  existing tests updated to the append semantics plus new URL cases
