fix(console): fix shrinking hover background on clear flow button (#10269)

## Problem
The mat-icon-button in the actions flow-type section had a shrinking
hover background. The hover effect was not displaying properly and
appeared constrained.

## Root Cause
The margin rules were being applied to all `span` elements, including
the Material button's internal elements (like `.mat-mdc-button-label`),
which interfered with the button's hover background positioning.

## Solution
- Changed the span selector from `span` to `> span` to target only
direct children
- Added specific margin reset for the button (`margin-right: 0`)
- Added margin reset for the icon inside the button
- This allows the Material button to use its default hover behavior

## Testing
- [x] No visual regressions in text spacing or layout
- [x] Button hover background now displays as a proper circle
- [x] Other buttons on the page remain unaffected
- [x] Matches the behavior of working buttons in trigger sections

## Type of Change
- [x] Bug fix (non-breaking change which fixes an UI issue)
