feat(dashboard): show custom track-event properties on tool invocations

[marselsel]

Why

Integrators that disable input/output capture — for privacy policies or app-store requirements — report curated fields through yavio.track() instead. Those events land in ClickHouse (events.metadata) but the dashboard never rendered them anywhere. The result: a privacy-conscious integration's invocations all show "No input/output data captured for this invocation", and the data it deliberately does send (e.g. Shipal's carrier, status, user_intent, latency_ms) is invisible.

What

A custom track() event fired inside a tool handler shares the invocation's trace_id (the SDK's AsyncLocalStorage trace context). The expanded invocation row in the tool-detail view now:

• fetches sibling track events for the listed traces (one extra paged query, trace_id IN (...), same time window — a track event shares its call's timestamp to within the handler's runtime)
• renders each one as a named badge + key-value grid (Custom Events)
• renders the tool_call event's own metadata when non-empty (Properties)
• keeps the honest empty state when nothing at all was captured, and keeps the input/output note when only custom events exist

Values are integrator-supplied content and are rendered as plain text only.

Tests

• queryToolRecentInvocations: joins custom events by trace id (dedup, empty-trace skip, mapping to the right invocations) — 3 new/updated cases
• Full dashboard suite: 512 passed; typecheck and biome clean

Rider

Second commit adds .claude/settings.local.json to .gitignore (personal Claude Code settings; must never land in a public repo).

Verified against production data: Shipal Prod events confirm the two-events-per-trace shape this renders.
