test(web): src/hooks/ is outside the coverage gate — two hooks (useServerJsonImport, useImportClientConfig) have no tests #1787

Summary

clients/web/src/hooks/ is not listed in the v8 coverage include in clients/web/vite.config.ts, so its four modules (917 lines) fall outside the per-file ≥90 gate — silently. Two of them have no test file at all. This is the live instance of the whitelist caveat documented by #1776 (PR #1784): a module outside components/lib/utils/server is ungated with no warning.

Surfaced during the #1776 review (PR #1784, round 7).

Current state

src/hooks/usePaginatedList.ts      + usePaginatedList.test.tsx     ✓ tested (but ungated)
src/hooks/useScrollMemory.ts       + useScrollMemory.test.tsx      ✓ tested (but ungated)
src/hooks/useServerJsonImport.ts   (308 lines)  — NO test, ungated
src/hooks/useImportClientConfig.ts              — NO test, ungated

useServerJsonImport / useImportClientConfig are real logic (config/JSON import parsing + wiring), consumed by ServerImportJsonModal / ServerImportConfigModal. Some lines execute during those components' tests, but because include never names src/hooks/**, nothing is measured or enforced.

Proposed change

Either:

• (a) Add 'src/hooks/**/*.{ts,tsx}' to the coverage include in clients/web/vite.config.ts, and bring useServerJsonImport.ts and useImportClientConfig.ts to ≥90 on all four dimensions (lines/statements/functions/branches) with dedicated tests; or
• (b) If hooks/ is deliberately excluded, document why in AGENTS.md.

(a) is preferred — these are exactly the kind of stateful wiring the gate exists for.

Note

Kept out of PR #1784 (same out-of-scope reasoning applied to customHeaders / navigation.ts there). While in vite.config.ts, consider also normalizing the include bases (it mixes src/**, clients/web/server/**, and path.join(repoRoot, 'core/**') — all resolve, just untidy).

Acceptance

• src/hooks/** gated (or a documented exclusion).
• useServerJsonImport.ts and useImportClientConfig.ts at ≥90 on all four dimensions.
• npm run ci green.
