Improve web logging and add regression tests for simplified deployment

[jimmieme]

Summary

This PR improves observability and test coverage of space-web for the
simplified deployment mode (LAN-first, minimal dependency path).

What Changed

• Introduced a centralized logger with sensitive-field redaction:
  • src/utils/logger.ts
• Added helper modules to make request behavior deterministic and testable:
  • src/api/network.helpers.ts
  • src/pages/login/switchLogin.helpers.ts
• Refactored key flows to use structured logs:
  • login flow (core.vue, qrLogin.vue, switchLogin.vue)
  • network request path (src/api/network.js, src/api/rawrequest.ts)
  • upload path (src/business/fileUp/sequelUpUtilNew.ts)
• Added regression unit tests:
  • tests/logger.test.ts
  • tests/network.helpers.test.ts
  • tests/network.error-routing.test.ts
  • tests/gateway.call.helpers.test.ts
  • tests/switch-login.helpers.test.ts
• Updated deployment/runtime support files:
  • docker-entrypoint.sh
  • nginx.conf.template
  • src/config/networkConfig.ts
  • src/main.js
• Updated package.json and package-lock.json for test/runtime dependencies.

Why

Recent debugging showed that web failures in simplified mode were hard to trace
due to inconsistent logs and low test coverage in critical routing/error paths.
This change standardizes logs, reduces noisy console output, and adds targeted
regression checks.

Validation

• npm run test:unit passed (13 tests).
• npm run build passed.
• Web smoke checks passed (/, /space/status, /space/v1/api/gateway/ version/box/current).

Impact

• Scope is space-web only.
• No backend API contract changes.
• Main impact is improved diagnosability and safer behavior during LAN/
  simplified deployments.
