Add a print stylesheet for the builder resume draft

[telivity-otaip]

Why

Users already download .doc / .txt. Printing or “Save as PDF” from the builder is a common expectation, but the page chrome (nav, locks rail, match score) wastes paper and looks broken.

Size

M — CSS @media print (+ tiny optional class toggles).

Task

1. In web/index.html styles, add @media print rules that:
   • hide header, board chrome, drawer, settings, non-draft builder chrome
   • show the draft text (#rp2_edtext / builder editor) cleanly in black on white
   • avoid cutting mid-section when possible
2. Optional: a Print / PDF button near existing download actions that calls window.print() only when a draft exists.
3. Doctrine blurb unnecessary in print output — keep it product UI only.

Acceptance

• Print preview from builder is readable and mostly draft-only
• Board / Memory pages don’t spew broken layouts when printed accidentally (hide app chrome reasonably)
• No new dependencies; works in Chromium + Firefox print preview
• npm test passes

Out of scope

Pixel-perfect ATS templates; DOCX redesign; auto-apply anything.
