Removes two dead Remix routes and the helpers only they used.
`app/routes/sync.traces.runs.$traceId.ts` (`/sync/traces/runs/:traceId`)
and `app/routes/sync.traces.$traceId.ts` (`/sync/traces/:traceId`) were
added with the original ElectricSQL run page and lost their only
consumers when the dashboard hooks that called them were deleted.
Nothing in the repo references either route today.
Also removed, because the deleted routes were their only callers:
- `OtelTraceIdSchema`, `RESERVED_ELECTRIC_SHAPE_PARAMS`, `TraceScope`,
`buildElectricTraceWhereClause` from `app/v3/electricShape.server.ts`
(the file stays — `UNSAFE_REALTIME_TAG_CHARS` /
`sanitizeRealtimeTagForSql` / `sanitizeRealtimeTagsForSql` are still
used by `realtime.v1.runs.ts` and `realtimeClient.server.ts`)
- the loader-specific cases in
`apps/webapp/test/spanTraceRoutes.replicaLag.test.ts` and
`internal-packages/run-store/src/runOpsStore.routesSpanTraceReadView.replicaLag.test.ts`
`app/utils/longPollingFetch.ts` is untouched —
`realtimeClient.server.ts` still uses it. `runOpsStore.ts` /
`PostgresRunStore.ts` are untouched too; the unrouted-lookup mechanism
there is generic and stays.
As a plain code fact: the run lookup these loaders performed keyed on
`TaskRun.traceId` alone, which is not an index-backed query shape. That
is noted only as context for why the code is not worth keeping around
unused.
### Judgement call worth a maintainer's opinion
The request was specifically about `/sync/traces/runs/:traceId`, the
route that looks up a run by `traceId`. This PR **also** deletes its
sibling `/sync/traces/:traceId`. The reasoning:
- both routes came in with the same ElectricSQL run-page work
- both lost their only consumers in the same later commit
- neither has any caller anywhere in the repo
- they share the same helper module, so keeping one means keeping the
helpers half-used
If you would rather keep the sibling, reverting just that one file
deletion is easy and does not affect the rest of this PR — say the word
and I will restore it along with the helpers it needs.

## Testing
Verification run locally from the repo root:
| Command | Result |
| --- | --- |
| `pnpm run format` | clean, no changes produced |
| `pnpm run lint:fix` | clean |
| `pnpm run lint` | pass (exit 0, no findings) |
| `pnpm run typecheck --filter webapp` | pass |
| `pnpm run typecheck --filter @internal/run-store` | pass |
A ripgrep sweep for `sync.traces`, `sync/traces`, `syncTraceRunsLoader`,
`buildElectricTraceWhereClause`, `OtelTraceIdSchema` and
`RESERVED_ELECTRIC_SHAPE_PARAMS` (excluding `node_modules`) returns zero
hits.
**Not fully verified:** both edited test files are testcontainers suites
and need a Docker runtime, which was not available in my environment. I
confirmed each file *collects* correctly with exactly the three intended
remaining tests and no import errors — notably, dropping the
`session.server` / `controlPlaneResolver.server` / `longPollingFetch` /
`env.server` mocks does not break module loading for the surviving
loaders. The assertions themselves then failed only on `Could not find a
working container runtime strategy`. CI should be the real signal here.
Per `apps/webapp/CLAUDE.md`, `pnpm run build --filter webapp` was
deliberately not run.

## Changelog
Removed two unused sync routes left over from the original ElectricSQL
run page, along with the helpers and tests that existed only to serve
them. No behaviour change — neither route had any caller.

## Screenshots
_n/a — no user-visible surface changes._
