Refine Getting Started docs: typography, preview styling, content polish

Port reflex-web PR #1818 plus content polish across all Getting Started pages.

Typography & preview styling (docs/app + packages/reflex-ui-shared):
- Tighter headings (smaller, semibold) and lighter body weight
- Wider content column (42rem→52rem / 56rem→64rem); right sidebar moved
  from xl: to 2xl: so mid-width screens have more room
- Navbar tabs visible from md: (was xl:) so they don't collapse to a
  burger at medium widths
- Pill-style tabs (pill-tab / pill-tab-list); slate-tinted inline rt-Code;
  hover-reveal copy button with "Copy" label; softer borders
- docgen_pipeline: cleaner rx.el.div section/tabs renderers with
  consistent gap and padding

Getting Started content:
- Introduction: new tagline, pill tabs, slate highlight (was violet),
  tightened walkthrough, added "Keep learning" / "Ship faster with AI"
  CTA cards
- Installation: added ~3 min estimate, removed embedded video, rewrote
  as a single uv-based flow with <your-app> placeholder, promoted Rosetta
  + bun.exe notes to md alert blocks, added "Next" CTA
- Basics: added ~10 min estimate, flattened Prerequisites wrapper,
  consolidated four single-line setup steps, fixed `rx.app` typo, fixed
  three broken [`code`](link) markdown links (rx.el / rx.cond /
  rx.foreach were rendering empty), added two CTA cards
- Dashboard tutorial: added ~20 min estimate, trimmed ~180-line
  finished-app dump at top down to a one-sentence roadmap + link to
  #full-app, numbered Setup steps, promoted "What are you building?"
  from H3 to H2, renamed Conclusion → Full app + Recap, dropped
  Advanced Section stub, unified all 10 preview boxes (slate border,
  12px radius, 2em padding, spacing="4", rx.box wrap)

Sidebar order:
- Getting Started now lists Installation before Introduction
