Dashboard Cards: Activity Card tweak UI

[zwarm]

Closes #18307

This PR tweaks the Activity Card UI

• Tightens spacing
• Decreases icon size from 48dp to 40dp to match the Activity Log list view

Before Light	After Light

Before Dark	After Dark

To test:

1. Install the Jetpack app
2. Login with a wp account
3. Select a site in which you can access the activity log (manage content/admin)
4. Navigate to App Setting > Debug Settings
5. Enable dashboard_card_activity_log and restart the app
6. Navigate to Home
7. ✅ Verify that the activity card is matches the requested changes

Regression Notes

1. Potential unintended areas of impact
   Activity card does not have enough spacing

2. What I did to test those areas of impact (or what existing automated tests I relied on)
   Manual testing

3. What automated tests I added (or what prevented me from doing so)
   N/A

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

The new icons size looks good!

I think the new icon size does match.
I think in a future PR it would be good to also match the fonts.

🥳

I think we need an overhaul on the entire dashboard - the fonts are all over the place. :( For this card, I am using the styles defined for the other dashboard cards (posts)

Looks better thanks.

@zwarm that's correct, the type sizes should follow My Site Home dashboard, not activity log.

Agree type sizes look messy on Android right now. Intention was to have only 2 or 3. A case of a few too many designers and a few developers and missed communications. A good example for the design system discussion lately. Think we can revisit separately.
