## Summary
Dashboard surfaces handle buffered runs by falling back to the mollifier
snapshot:
- Run detail, span detail, streams view (`_app.../runs.\$runParam`,
`resources.../spans.\$spanParam`, `resources.../streams.\$streamKey`).
- Redirect routes (`@.runs.\$runParam`, `runs.\$runParam`,
`projects.v3.\$projectRef.runs.\$runParam`).
- Action routes — cancel / replay / idempotency-reset / debug — under
`resources.taskruns/...` and `resources.../idempotencyKey.reset`.
- Logs download.
- Realtime subscription route + per-run resource
(`realtime.v1.runs.\$runId`, `resources.../realtime.v1.*`).
- `CancelRunDialog` gains an `onCancelSubmitted` callback so submit
isn't raced by the Radix `DialogClose` wrapper.
Stacked on the mutations PR.
## Test plan
- [x] \`pnpm run typecheck --filter webapp\` passes
- [x] \`pnpm run test --filter webapp
test/mollifierRealtimeRunResource.test.ts\` passes
- [x] \`pnpm run test --filter webapp
test/mollifierRealtimeRunResourceBuffer.test.ts\` passes
- [x] \`pnpm run test --filter webapp
test/mollifierRealtimeSubscription.test.ts\` passes
- [x] Manual smoke: trigger a buffered run, open it in the dashboard,
replay/cancel from the UI

## Ship-gate follow-up fixes
- **Auto-redirect to root span on direct nav** — loader sets `?span=`
from root span (PG) or buffered snapshot spanId before 302'ing, so
bookmark/share-link/direct-nav doesn't leave the panel collapsed.
- **RunPresenter switches from `findFirstOrThrow` to `findFirst` + typed
`RunNotInPgError`** — kills the per-poll `PrismaClient error` log spam
for buffered runs without changing the route-loader's fallback flow.
- **Span detail panel renders for buffered runs** — `SpanPresenter.call`
now falls back to `findRunByIdWithMollifierFallback` +
`buildSyntheticSpanRun` instead of returning undefined and triggering
the "Event not found" toast loop.
- **Logs download for buffered runs returns a gzipped placeholder line**
— replaces the 404 with a content-encoded line explaining the run is
queued. Same org-membership gate as the PG path.
- **Admin Debug-Run button hidden for buffered runs + SpanRun circular
type alias broken** (squashed) — buttons gate on a new `isBuffered` flag
on the synthetic SpanRun. Required grounding SpanRun in
`SpanPresenter.getRun` to break a circular type alias TS no longer
tolerates once `isBuffered` is a literal field on the shape.
- **Replay action requires user auth + org-membership** (🚩 Devin
finding) — `action` was unauthenticated and the PG `findFirst` had no
org filter, so any caller with a valid `runParam` could replay any run.
Buffered fallback inherited the same gap. Fixed to mirror the cancel
route.
