fix(ai,pdf): heal malformed section content and add PDF export fallback

Fixes #87 and #85.

#87 — "打不开修好的简历" / AI generation errors:

• Add src/lib/resume/normalize-content.ts: coerce inner list fields
  (highlights/technologies/skills) to arrays so AI-written strings can't
  crash the template renderers.
• Apply on read (resume-store, preview page) to heal already-corrupted
  resumes, and on write (updateSection/rewriteText/translateResume,
  generate-resume route) to prevent new corruption.
• Wrap the preview in a PreviewErrorBoundary and harden isSectionEmpty so
  a bad section degrades to an inline message instead of the full-page
  error screen.
• generate-resume robustness: raise output token cap, retry without
  json_object for OpenAI-compatible endpoints that reject it, surface the
  real error message.

#85 — PDF / 智能一页 export 502:

• Add a client-side "print to PDF" fallback in the export dialog for when
  server-side Chromium is unavailable/OOM (fetches print HTML into a
  hidden iframe and opens the browser print dialog).
• getBrowser() no longer blindly trusts CHROME_PATH (verify + fall through
  to candidates); export route returns the real error.
• Remove stray UTF-8 BOM from generate-pdf.ts.

Tests: normalize-content unit tests + updateSection regression cases.
