configurable kg / meeting / track-block model overrides

Bring back per-category model selection that 5c4aa772 dropped, plus add a
new track-block category. Each is a BYOK-only override on `LlmModelConfig`
(`knowledgeGraphModel`, `meetingNotesModel`, `trackBlockModel`); signed-in
users always get the curated gateway default and never hit the on-disk
config.

Three helpers in core/models/defaults.ts — `getKgModel`,
`getTrackBlockModel`, `getMeetingNotesModel` — each check `isSignedIn`
first (fast path) and fall through to `cfg.<field> ?? cfg.model` for BYOK.

The model is now picked at the invocation site rather than via runtime
agent-name branching: each top-level `createRun` for a polling KG agent
or a track-block update passes `model: await getXxxModel()`. The `model:`
declarations on the affected agent YAMLs are dropped — they were dead
code under the per-call override. Standalone (non-run) callers
`track/routing` and `summarize_meeting` use the helpers inline.

Settings dialog and the two onboarding flows surface the two new fields
("Meeting Notes Model", "Track Block Model") next to the existing
"Knowledge Graph Model"; `repo.setConfig` persists all three per-provider.

Note: the signed-in `RowboatModelSettings` panel still has its
now-defunct kg selector; that's a UI cleanup for a later pass.
