fix(deps): resolve all 18 Dependabot alerts

[khaosdoctor]

Fixes all 18 Dependabot alerts GitHub flagged on main (1 critical, 3 high, 10 moderate, 4 low). All of them were transitive build tooling deps, nothing in the worker runtime.

What changed:

1. Bumped wrangler to 4.110.0 and @cloudflare/workers-types to 5.x together, the old pair was blocking the rest of the fixes from resolving
2. Bumped all @docusaurus/* packages to 3.10.2
3. Added an overrides block for serialize-javascript, uuid, and esbuild, those three were still pinned to old versions deep inside Docusaurus own dependency tree and npm audit fix wanted to downgrade Docusaurus itself to get rid of them, which is backwards

npm audit now reports 0 vulnerabilities. Typecheck, full test suite, full build (all 3 locales plus the worker bundle), and lint all pass clean.
