perf(console-ui): tune TanStack Router and Query

[malinskibeniamin]

Summary

• Upgrade @tanstack/react-query and its devtools from 5.99.x/5.90.x to 5.101.2.
• Share one Router plugin configuration between Rsbuild and Vitest, use the current Rspack plugin export, ignore test/helper route files, and emit a stable async lib-tanstack vendor chunk.
• Enable intent preloading while setting defaultPreloadStaleTime: 0, keeping TanStack Query responsible for cache freshness.
• Wire the existing pending and error route boundaries into both standalone and embedded routers; make the pending state natively announced to assistive technology.

This keeps the scope to the critical Router/Query integration from TanStack Router and Query. Existing awaited ensureQueryData loaders remain unchanged because they already follow the supported integration pattern.

Screenshots / surface review

View	Before	After	Notes
Route pending state	Existing spinner and “Loading...” copy	Visually unchanged	Screenshot skipped: only native status semantics changed; classes and copy are unchanged. Covered by an accessibility-focused integration test.

Visual recap skipped: this is dependency/build/runtime configuration work with no visual delta.

Dependency upgrade path

• Upgrade evidence: lockfile regenerated with Bun; no call-site migration or codemod was required for Query 5.101.2.
• Packages: @tanstack/react-query 5.99.2 → 5.101.2; @tanstack/react-query-devtools 5.90.2 → 5.101.2.
• SemVer confidence: same major version, release notes reviewed, full type/unit/integration/build verification completed.
• Risk gate: Router remains on 1.170.17. The newer 1.170.18 release is below this repository's 72-hour minimum release-age gate, so this PR does not bypass the supply-chain safeguard.
• Security notes: bun audit reports existing repository-wide advisories; none are introduced by this focused TanStack update.

Test plan

• bun install --frozen-lockfile --ignore-scripts
• bun run type:check
• Ultracite check on new/changed Router configuration and tests
• Unit suite: 57 files, 863 tests
• Integration suite: 115 files, 1,188 tests
• Production build
• Bundle comparison: total gzip decreased by about 24 kB; entry bundles stayed effectively flat; TanStack dependencies now form an async cached vendor chunk

Local Node 25 requires --localstorage-file for the pre-existing topic-settings-store integration test; the isolated failure passes with that harness option.
