feat: migrate to Node.js 24 LTS

[smdion]

Summary

• Dockerfile: node:20-alpine → node:24-alpine (all 3 stages)
• CI: node-version: 20 → 24
• @types/node: 20.x → 24.x

Node 20 reaches EOL April 30, 2026. Node 24 is the current Active LTS with support through April 2028.

Verified locally

• Type-check: clean
• Full test suite: 2,326 passed, 0 failed
• Next.js 14 engine requirement is >=18.17.0 — Node 24 is compatible

Test plan

• CI passes (type-check, lint, build, tests, E2E)
• Docker build succeeds (validates better-sqlite3 native addon compiles on Node 24 alpine)
• Health endpoint returns correct version after deploy

In `@package.json`:
- Line 63: The dependency "better-sqlite3" pinned at version "12.8.0" is
incompatible with Node.js 24; update package.json to use a better-sqlite3
release that officially supports Node 24 (or change the runtime Node version).
Locate the "better-sqlite3" entry in package.json and replace "12.8.0" with a
compatible version from the better-sqlite3 releases (or update your engines
field or CI/runtime to a supported Node LTS), then run npm/yarn install and
rebuild to verify the native module compiles successfully.
