Feat/decrease paragraph min width

[creativoma]

Description of change

This PR addresses issue #656, which requested a reduction in the minimum width for paragraphs, text components, and inputs.

---

Changes Made:

1. Centralized Constant:

   • Introduced DEFAULT_MIN_WIDTH in BASIC_SHAPE to define a shared minimum width for all relevant components.
   • Ensures consistency and avoids magic numbers.

2. Updated Components:

   • Refactored the following components to use the centralized constant:
     • TextAreaShape
     • TextScribbledShape
     • ParagraphShape
     • SmalltextShape
     • Other related shapes.

3. Improved Maintainability:

   • Removed hardcoded values for minWidth across components.
   • Ensured all shapes now reference BASIC_SHAPE.DEFAULT_MIN_WIDTH.

---

Technical Implementation:

• Updated shape.const.ts to include DEFAULT_MIN_WIDTH in BASIC_SHAPE.
• Refactored ShapeSizeRestrictions in all relevant components to use the centralized constant.
• Verified that no other components were missed during the refactor.

---

Test Results:

• Unit Tests:
  • ✅ All existing tests passed (npm run test).
• E2E Tests:
  • ✅ Verified no regressions using Playwright (npm run e2e).
• Manual Testing:
  • ✅ Confirmed minimum width is applied correctly across all affected components.

Closes #656.
