fix(task-list): set custom column initial width to 180px and minimum width to 100px

[ThishankaM]

• Initialize newly created custom columns with 180px default width to prevent inline action button shifting
• Enforce 100px minimum width constraint for custom column resizing
• Prevent check and cancel action buttons from wrapping/shifting in CustomColumnHeader
• Update column width validation utility and unit tests

Summary by CodeRabbit

• Improvements
  • Custom columns can now be resized down to 100px, instead of a 180px minimum.
  • New custom columns retain a default width of 180px, with the existing 400px maximum.
  • Column header save and cancel buttons no longer shrink or wrap.

📝 Walkthrough

Walkthrough

Custom-column width limits and defaults now use shared constants. The minimum width is 100px, the default is 180px, and the maximum remains 400px. Custom-column creation and editing components use these values.

Custom-column widths

Layer / File(s)	Summary
Shared width values and validation worklenz-frontend/src/utils/column-width-validation.ts, worklenz-frontend/src/utils/__tests__/column-width-validation.test.ts	The minimum width changes from 180px to 100px. The default is defined as 180px, and tests expect below-minimum widths to clamp to 100px. The maximum remains 400px.
Width usage in custom-column UI worklenz-frontend/src/components/task-list-v2/TaskListV2Table.tsx, worklenz-frontend/src/components/task-list-v2/components/CustomColumnComponents.tsx, worklenz-frontend/src/pages/projects/projectView/taskList/task-list-table/custom-columns/custom-column-modal/add-custom-column-button.tsx	The task table and column creation and editing components use the shared width constants. The inline header editor disables wrapping and prevents its save and cancel buttons from shrinking.
