feat(log): show custom attributes in log view

[betegon]

sentry log view showed a fixed set of fields. Custom attributes users attach to their logs — visible in the Sentry UI — were never fetched or displayed.

sentry log list already supported custom attributes via --fields before this work. No changes there.

How it works

The Sentry UI calls a trace-items detail endpoint when expanding a log row:

GET /projects/{org}/{project}/trace-items/{itemId}/?item_type=logs&trace_id={traceId}

It returns every attribute on the log without needing to enumerate field names. log view now does the same: after getLogs fetches standard fields (including trace), getLogItemDetail is called in parallel for each log. formatLogDetails renders all non-standard attributes in a Custom Attributes section automatically. --fields filters that section when you only want specific attributes.

The endpoint is EXPERIMENTAL in Sentry and not yet in @sentry/api (generated from getsentry/sentry-api-schema), so it uses apiRequestToRegion directly — same pattern as listTraceLogs. Attribute types mirror TraceItemResponseAttribute:
https://github.com/getsentry/sentry/blob/8a4f150b21b/static/app/views/explore/hooks/useTraceItemDetails.tsx#L85-L89

If the endpoint is unavailable (no trace ID on the log, or request fails), the formatter degrades gracefully and shows only standard fields.

Type consolidation

PR #623 defined TraceItemAttribute and TraceItemDetail as plain TS types in traces.ts. This PR moves them to src/types/sentry.ts with Zod schemas (.passthrough() so meta/links from the spans endpoint are preserved), exports them via the types barrel, and re-exports from traces.ts for existing callers. getSpanDetails also gets schema validation for parity with getLogItemDetail.

Usage

# Shows ALL custom attributes automatically — no config needed
sentry log view myorg/myproject <id>

# Limits the Custom Attributes section to specific fields
sentry log view myorg/myproject <id> --fields order.id,user.tier

# JSON output: unchanged
sentry log view myorg/myproject <id> --json
