chore: revert frontend UI changes to 7aa0d90 to fix layout blowout

Add missing UI buttons: paragraph spacing, Arabic tools (tashkeel, numerals, cleanup), sparkline container

Wire up all 8 missing UI elements: Arabic tools dropdown, paragraph spacing, typewriter mode, version history buttons, error chart + sparkline hooks

Implement all 19 remaining UI features: toolbar tools, find/replace, focus mode, error tabs, donut chart, version history, Arabic tools, tab animations, etc.

Enhanced toolbar: tab icons, section labels, custom tooltips, lists, RTL/LTR, link, line height

Hide docs sidebar + expand layout to full width in non-write tabs (tools-mode)

Center tabs, hide doc title, add dot hover glow animation, center format toolbar

Add 'Apply to editor' for summary panel (replaces original text with summary)
