Drop the database name from single-database document output

Naming one database on the command line points the configuration at it,
so no command that prints a document ever has a name to print.

 - `api_key` on model and embedding-model config, overriding the provider's environment variable. Honored on the `openai` and `ollama` providers, `vllm` embedders and rerankers, the picture-description VLM endpoint, and `doctor`'s endpoint probes; other providers raise.
-- `lancedb.databases`: a name-to-location mapping for searching several databases at once, mutually exclusive with `lancedb.uri`. `client.search(..., sources=[...])` selects which to search, `sources=None` searches all of them, and `SearchResult.source` carries the configured name a result came from. `Document.source` names it on a document from a listing or a lookup. Candidates are fused by the configured reranker over the union, or by reciprocal rank fusion when none is configured. Databases searched together must have been written with the same embedder; two that disagree raise `ConfigMismatchError`. The query is embedded once for the whole selection. `SearchResult.format_for_agent` names the database, so the model can attribute evidence to one while it answers. `haiku-rag search`, `ask`, `analyze` and `chat` cover the configured set and label each result and citation with its database; every other command works on one, named with `--database NAME` or `--db PATH`.

 - `client.ask(..., sources=[...])` asks across the selected databases, and `Citation.source` names the one a cited chunk came from. The cite fallback for an id absent from the run's results looks only in the selected databases, so a question scoped to some cannot cite another.
 - `client.analyze(..., sources=[...])` analyzes across the selected databases: the sandbox mounts their documents under one flat `/documents/{id}/` namespace, resolving each id to the database holding it, and in-code `search()` covers the same selection.

 compares ranks, not scores, so every database contributes its own best matches
