fix: PPTX watermark + black slide + pricing page /pricing

- export-pptx.ts: fix watermark position for LAYOUT_WIDE (13.33"×7.5")
  → moved from y:5.35 (71% height) to y:7.1 near bottom-right (x:10.0)
- export-pptx.ts: fix buildSummarySlide dark background (T.primary overlay
  covered 100% of slide appearing black) → cream bg with colored stat cards
  matching design of other brainstorm slides
- pptx.tool.ts: fix addImageFullSlide using t.primary as bg when no imageUrl
  → falls back to t.bg (light); text colors adapt accordingly
- pricing/page.tsx: create /pricing standalone page reusing exact landing
  page pricing section (PLANS array, billing toggle, i18n keys)
