fix(dashboards): fix text card overlapping edit button (closes #26285, #26413)

[thmsobrmlr]

Problem

The content of text cards can overlap the edit button. This is most notable for text cards with code blocks.

• fix(dashboards): Ensure editing controls are always visible on TextCards #26413

Changes

• Adds a padding on the right side of the content, so that it doesn't overlap the button.
