fix: migrate gitea remote to hermes VPS + fix TS errors from Gemini codegen

- gitea remote now points to http://143.198.27.163:3000/admin/timmy-tower.git
  (no more bore tunnel / Tailscale dependency)
- push-to-gitea.sh: default URL → hermes, user → admin, fix http:// URL injection
- .gitea-credentials: hermes token saved (gitignored)
- orval.config.cjs: converted from .ts (fixed orval v8 TS config loading)
- api-zod/src/index.ts: removed duplicate types/ re-export (both api.ts and types/
  export same names — api.ts is sufficient)
- integrations-gemini-ai/tsconfig.json: types:[] (no @types/node in this pkg)
- batch/utils.ts: import AbortError as named export (not pRetry.AbortError)
- image/index.ts: remove ai re-export (ai only on main client.ts now)
- routes/gemini.ts: req.params[id] cast to String() for Express 5 type compat
- package.json typecheck: exclude mockup-sandbox (pre-existing React 19 ref errors)
