fix(editor): position description toolbar button on left border

[Rishavraaj]

Summary

• The EditorJS + toolbar button was appearing on the right side of the description field in the task create sheet due to EditorJS's
  mobile/narrow layout fallback (right: auto with no left set)
• Fixed by positioning the button flush against the left border of the description container — left: 0 on .ce-toolbar__actions with the
  container's left padding removed (pl-0) so the button sits on the border without overlapping text
• Scoped all CSS changes to [id^="task-description-editor"] (matches both the create form and detail view editors) to prevent bleeding into
  other EditorJS instances (e.g. deal/company/contact description editors)

Changes

• globals.css — Add scoped CSS for task description editors: position toolbar actions on the left, hide the settings/drag button, and indent
  block content by 30px to clear the + button
• TaskForm.tsx — Remove left padding (pl-0) from the description container so the editor starts flush with the border
• TaskDetail.tsx — Same pl-0 treatment for the task detail description editor

Test plan

• Open the Create Task sheet — description field should show + button on the left border with placeholder text starting after it
• Open a Task Detail view — description editor should have the same left-border button placement
• Verify other editors (deal description, contact description, company description) are unaffected
• Confirm no horizontal overflow/scrollbar appears in the description fields
• Check both light and dark mode
