Add unit tests for the backend pagination clamping, defaults, and meta math

[1nonlypiece]

📌 Description

src/lib/backend/pagination.ts parses page/limit params and computes pagination meta, but it has no co-located test. Clamping, defaults, and meta math are unverified.

🎯 Requirements and Context

• Cover default page/limit and clamping of out-of-range values.
• Assert total-pages and hasNext/hasPrev meta computation.
• Cover invalid (non-numeric) inputs falling back to defaults.

🛠️ Suggested Execution

1. Fork the repo and create a branch

git checkout -b test/backend-pagination-tests

2. Implement changes

• src/lib/backend/__tests__/pagination.test.ts — new unit test
• src/lib/backend/pagination.ts — read only

3. Test and commit

• Run the suite: pnpm test (or npm test) and pnpm lint.
• Cover edge cases: limit above max; page below 1; non-numeric params; zero total items.
• Include test output (and a short note of any behavioural findings) in the PR.

Example commit message

test: add unit coverage for backend pagination parsing and meta

✅ Guidelines

• Minimum 95% test coverage on the new/changed lines.
• Clear, reviewer-friendly documentation and a small, focused diff.
• No regressions against existing suites.
• Timeframe: 96 hours.
