fix(ui): unblock Cloudflare Pages build (eslint 10 peer conflict)

[adityak74]

Problem

The Cloudflare Pages build is failing on main. It never reaches the build step — it dies during dependency install.

Reproduced locally against origin/main (018a6fc):

$ cd ui && npm ci
npm error code ERESOLVE
npm error While resolving: eslint-plugin-react-hooks@7.0.1
npm error Found: eslint@10.8.1
npm error Could not resolve dependency:
npm error peer eslint@"^3.0.0 || ... || ^9.0.0" from eslint-plugin-react-hooks@7.0.1

Root cause

A Dependabot bump moved ui/ to eslint@^10.8.1, but left eslint-plugin-react-hooks at ^7.0.1, whose peer range stops at eslint 9:

7.0.1 → ^3.0.0 || ^4.0.0 || ^5.0.0 || ^6.0.0 || ^7.0.0 || ^8.0.0-0 || ^9.0.0
7.1.1 → ^3.0.0 || ^4.0.0 || ^5.0.0 || ^6.0.0 || ^7.0.0 || ^8.0.0-0 || ^9.0.0 || ^10.0.0

npm ci refuses the install, so Pages fails before vite build runs.

Fix

Bump eslint-plugin-react-hooks to ^7.1.1. That is the whole change.

I checked the rest of the eslint stack rather than bumping blindly — nothing else needed changing:

Package	eslint peer range	eslint 10 OK?
typescript-eslint@8.67.0	^8.57.0 || ^9.0.0 || ^10.0.0	✅ already
eslint-plugin-react-refresh@0.4.24	>=8.40	✅ already
eslint-plugin-react-hooks@7.0.1	… || ^9.0.0	❌ the blocker

Verification

Run against origin/main with this patch applied:

• ✅ cd ui && npm ci — succeeds (was the failing step)
• ✅ cd ui && npm run build — tsc -b && vite build, built in 357ms
• ✅ npm ci at repo root — succeeds
• ✅ npm run build at repo root — succeeds

Note on lint (not addressed here, and not blocking)

npm run lint reports errors, but this is pre-existing and unrelated to the deploy:

• Baseline on origin/main (forced install via --legacy-peer-deps): 27 errors
• With this patch: 32 errors

The 5 additional errors come from new rules shipped in react-hooks 7.1.x (react-hooks/immutability, react-hooks/error-boundaries), not from anything this PR changes in application code.

Lint is not part of the Pages build (npm run build is tsc -b && vite build) and there is no lint CI workflow, so none of this blocks the deploy. Worth a separate cleanup PR — deliberately left out of this one to keep the deploy fix minimal and easy to review.

Superseded by #25, which carried this fix in as 4199652. main already reads eslint-plugin-react-hooks ^7.1.1, so this PR is now a no-op.
