test(storage): give the policy suite an explicit harness budget (lidge-jun#732)

seedHome() writes real files and a sqlite fixture per case. On a slow
windows-latest runner those cases take 6-8s against bun's 5s default and fail
deterministically (run 30507689929 failed the same five twice, the second time
after a --failed rerun) while a faster runner passes the identical code —
locally the file is 22 pass in ~100ms.

The sibling storage-cleanup suite already carries { timeout: 20_000 } /
{ timeout: 30_000 } on its seeding-heavy cases with a comment naming the same
cause. This file had no budget at all, so one file-level setDefaultTimeout(30_000)
covers all fifteen seedHome sites. setDefaultTimeout is the existing convention
here (grok-management-api, codex-history-provider, claude-management-api,
server-combo-failover-e2e, subagent-fallback-handle-responses all use 30_000).

Test-harness only: no src/storage change, since nothing indicates the selection
logic is wrong.

Closes lidge-jun#727
