nwhitehouse wires in a self-hosted reasoning model

- New OLAVA provider (vLLM/OpenAI-compatible) wired through types,
  models registry, llm/index router, and a streaming client. Handles
  reasoning-model output: drops `delta.reasoning` /
  `delta.reasoning_content` from emitted text, strips inline
  <think>...</think> blocks, defaults max_tokens to 16384 with
  OLAVA_MAX_TOKENS env override, and logs per-iteration content vs
  reasoning byte counts. Surfaced as "Olava Extract" in the tabular
  review model dropdown only (deliberately omitted from main chat).
- GET /user/server-keys reports which provider keys are present in
  .env (booleans only, placeholder values filtered) so the frontend
  can mark env-configured providers as available without requiring
  per-user keys. Threaded through UserProfileContext, ModelToggle,
  TabularModelDropdown, and the four call sites that build the
  apiKeys check.
- forcePathStyle on the S3Client in both backend and frontend so
  MinIO works as a local R2 substitute (R2 accepts path-style too).
- Frontend dev script binds to port 9000; backend reads PORT (9001).
- supabase/ config.toml + .gitignore from `supabase init` for the
  local Postgres+Auth+Storage stack.

- completeOlavaText takes max(caller, OLAVA_MAX_TOKENS) so callers
  tuned for non-reasoning models (e.g. tabular regen passing 2048)
  don't undershoot the reasoning budget.
- Strip tools from the request body by default - vLLM rejects with
  HTTP 400 unless launched with --enable-auto-tool-choice. Set
  OLAVA_ENABLE_TOOLS=true to pass tools through when the server is
  configured for them.
- Olava is now offered in the main chat model dropdown alongside
  Anthropic and Google. ApiKeyMissingModal shows a server-config
  message for Olava (env vars) instead of pointing at account
  settings.
- Per-iteration log dumps the truncated response text to make
  diagnosing short / refusal responses straightforward.

- Olava tool-call plumbing: switch to non-streaming when tools are
  forwarded (vLLM streaming with --enable-auto-tool-choice silently
  drops the parsed tool_calls payload, even though it sets
  finish_reason="tool_calls"). Single round-trip per iteration is
  more reliable.
- Custom client-side parser for the LoRA's <tool_call><function=...>
  <parameter=...> token format, generic across every tool. Iteratively
  strips trailing </parameter> / </function> / </tool_call> tags so
  values like read_document's docLabel aren't poisoned with markup.
  JSON-decodes parameter values, with scalar coercion fallback.
- generate_docx now parses **bold** markdown in section content via a
  small TextRun splitter so party names / defined terms render bold
  instead of leaking literal asterisks into the .docx.
- System prompt: demoted the "MUST call read_document after
  generate_docx" rule to "MAY", and explicitly forbids re-issuing
  generate_docx in the same turn to "fix" perceived imperfections -
  use edit_document or just describe the issue. Stops the model from
  emitting two duplicate downloads when it self-critiques.
- Tabular review: new "Wrap text" toolbar toggle (cells switch from
  line-clamp-1 to wrap-and-grow). Header columns are drag-to-reorder
  via HTML5 DnD, persisted through the existing columns_config saver;
  display order follows the array, cell lookup keeps using the stable
  .index. Per-column resize via a hidden right-edge drag handle with
  a 120px floor; widths are local state.
