* feat(providers): api_surface toggle + mistral medium reasoning fix

Mistral medium open-weights served by vLLM expects reasoning_effort via
the Responses API (`reasoning.effort`), not as a `chat_template_kwargs`
entry on Chat Completions.  The session was unconditionally injecting
`{"reasoning_effort": ...}` into `chat_template_kwargs` for every
openai-compatible request, which corrupted the prompt rendering for any
backend whose chat template didn't consume that key (Mistral medium,
Mistral cloud, Groq, OpenRouter).

Changes:
- Add `api_surface` ("chat" | "responses") to `ModelConfig.server_compat`
  and thread it through `create_provider` / `model_registry.get_provider`.
  `openai-compatible` defaults to Chat Completions; operators can flip
  individual aliases to Responses for endpoints that support it.
- New `vllm-mistral-medium` profile that pre-fills api_surface=responses
  on Detect for known Mistral medium model ids.
- Drop the unconditional `reasoning_effort` injection into
  `chat_template_kwargs`.  Operators running gpt-oss-style local
  templates that consume `reasoning_effort` from the chat template now
  opt in via `server_compat.extra_body.chat_template_kwargs`.
- New "API Surface" select in the Models admin tab; allowlist-validated
  server-side at create/update time; pre-filled by Detect via the
  profile suggestion.
- Evict the cached provider singleton in `ModelRegistry.reload()` when
  api_surface changes (previously only cfg.provider triggered eviction).
- Fix `_run_agent` fallback path to inherit the session's primary alias
  for capability and server_compat resolution; previously the fallback
  passed `alias=None`, which silently dropped per-model caps on the
  agent path.

Tests: 5117 passed (-m "not live"); ruff + mypy clean.

* fix(providers): don't auto-suggest Responses for Mistral medium

vLLM's Responses API surface for Mistral medium open-weights doesn't
wire up the Mistral tool-call parser as of vLLM 0.x — tool calls leak
into the response as ``[TOOL_CALLS]<name>{...}`` text instead of
structured tool_calls.  Chat Completions on the same engine handles
tools cleanly via ``--tool-call-parser mistral``, and reasoning can be
turned on via the vLLM CLI ``--reasoning-parser`` flag.

Drop the auto-suggest mapping so Detect falls back to the generic
``vllm`` profile.  Keep the ``vllm-mistral-medium`` profile definition
in place so an operator who specifically wants per-request effort and
accepts the tool-calling limitation can still pick "Responses API"
manually in the admin UI.

* fix(providers): address Copilot review on PR #469

- providers/__init__.py: drop the redundant *_responses_provider /
  *_chat_provider names; have create_provider use _openai_provider and
  _openai_compat_provider directly so they're not flagged as unused
  globals.
- console/server.py: tighten _validate_api_surface to a strict equality
  match against the canonical {"chat", "responses"} set.  The previous
  strip().lower() membership check accepted ' Responses '/'CHAT' but
  stored the raw string verbatim, which then failed to round-trip
  through the admin <select>.
- console/static/admin.js: gate the entire server_compat block (server
  type, api_surface, extra_body) on provider == "openai-compatible" at
  save time so toggling provider away can't leave a stale hidden surface
  selection in the persisted capabilities JSON.
- tests/test_session.py: splat the bad kwarg via **dict so CodeQL no
  longer flags the call as a wrong-name keyword (the point of the test
  is the runtime contract, not the static type).
- tests/test_admin_model_registry_refresh.py: add endpoint-level tests
  for the api_surface validation on both create and update — covers the
  bogus-value rejection, non-canonical-string rejection, and the happy
  path persisting through to the refreshed registry.

* feat: pass resolved capabilities through to providers, add server compat layer

The LLMProvider protocol previously forced providers to re-derive
capabilities from static lookup tables, ignoring config overrides set
via the admin UI or config.toml (e.g. thinking_mode, token_param).
This adds an optional capabilities parameter to create_streaming and
create_completion so the session can pass its config-merged
ModelCapabilities through to providers.

On top of this, adds a server compatibility layer for local model
servers (vLLM, llama.cpp). Profiles suggest thinking mode and server
workarounds (skip_special_tokens for vLLM, reasoning_format for
llama.cpp) during model detection, with structured admin UI fields
for server type, thinking mode, and extra body params.

Verified against real vLLM (Gemma 4 31B) and llama.cpp (Gemma 4 E4B)
servers.

* fix: defensive copy in _finalize_extra_body, expose thinking_param in UI

Shallow-copy extra_params and its chat_template_kwargs in the provider
before _apply_thinking_mode mutates them, so callers that reuse the
same dict across models are safe.

Replace the hidden thinking_param input with a visible text field
that appears when thinking mode is enabled. Shows the default
"enable_thinking" and hints that Granite/DeepSeek use "thinking".

* fix: address Copilot review feedback on admin UI and server compat

- Preserve unrepresentable thinking_mode values (e.g. "adaptive") in
  raw capabilities JSON instead of silently dropping on edit round-trip
- Validate capabilities and extra body JSON are plain objects, not
  arrays or primitives
- Deep-merge chat_template_kwargs from extra_body instead of silently
  dropping, so operators can extend/override template kwargs

* fix: hide server compat section for non-local providers

The Server Compatibility fields (server type, thinking mode, extra
body) only apply to openai-compatible (local model servers). Hide
the entire section when the provider is openai, anthropic, or google.

* fix: normalize capsObj to plain object on edit load

Defend against DB rows where capabilities is a JSON literal null,
an array, or a primitive — previous code would crash on the
capsObj.server_compat / capsObj.thinking_mode reads. Same defensive
check also applied to the server_compat nested value.

* refactor: extract _isPlainObject helper for JSON type checks

Consolidates the null/array/typeof check that was inlined at three
different call sites into a single helper. Keeps the intent obvious
at each use site and avoids the awkward multi-condition ternary.
