Fix code block rendering inconsistencies and update page title on custom components command reference

[devin-ai-integration]

Fix visual inconsistencies in code block rendering on custom components command reference page

Summary

Fixed visual inconsistencies in code block rendering on the /docs/custom-components/command-reference/ page that were causing some code blocks to appear empty or inconsistently styled. The issue was caused by mixing different rendering approaches (doccmdoutput(), rx._x.code_block(), and standard markdown) on the same page.

Key Changes:

• Standardized all code blocks to use consistent markdown formatting with proper language specifications
• Updated page title to "Custom Component CLI Reference" for better clarity
• Removed unused Python exec imports
• Converted doccmdoutput() function calls to standard bash + text code block pairs
• Added missing language specifications to prevent empty code block rendering

Risk Level: 🟡 Medium - Documentation system complexity and potential for markdown parsing edge cases

Review & Testing Checklist for Human

• Visual verification across browsers: Test the page in Chrome, Firefox, Safari to ensure all code blocks render correctly and consistently
• Content accuracy verification: Compare the static command outputs in the markdown with actual reflex component --help, reflex component init --help, etc. outputs to ensure they match
• Page title verification: Confirm "Custom Component CLI Reference" displays correctly in browser tab and navigation breadcrumbs
• Regression testing: Check 2-3 other documentation pages to verify no visual regressions in code block rendering
• Mobile responsiveness: Test the page on mobile devices to ensure code blocks don't break layout

Notes

• Root cause: Mixed rendering approaches on same page caused inconsistent styling and empty code blocks
• Testing approach: Verified locally using reflex run development server - all code blocks now display correctly
• Content preservation: All command examples and outputs maintained, just converted from dynamic generation to static markdown
• Session details: Requested by Alek, developed in Devin session: https://app.devin.ai/sessions/e4bf82db93214fed9429c5319264df84
• Before/after comparison: Screenshots show clear improvement from empty/inconsistent blocks to properly rendered content
