Follow-up to #8317 -> addresses reviewer feedback regarding the "Hide Sharing Actions" setting.
closes #7136 (the share button feature was added in #8317, this PR fixes a missing setting check)

Description

The share button I added to community posts in #8317 doesn't get hidden when "Hide Sharing Actions" is enabled in Distraction Free settings. This fixes that by adding the same v-if check used by the other share buttons throughout the app.

Testing

1. Open FreeTube and navigate to a channel with community posts (e.g., https://www.youtube.com/channel/UCQeRaTukNYft1_6AZPACnog)
2. Go to the Posts tab
3. Verify the share button is visible next to community posts
4. Go to Settings → Distraction Free Settings → Hide Sharing Actions and enable it
5. Go back to the channel's Posts tab
6. Verify the share button is now hidden on community posts
7. Disable the setting again and verify the share button reappears

Desktop

• OS: Windows 11
• OS Version: Windows 11 24H2 (OS Build 26100.7171)
• FreeTube version: 0.23.15 (development build)

Additional context

This is a minimal 2-line change:

1. Added v-if="!hideSharingActions" to the <FtShareButton> in the template
2. Added a computed property hideSharingActions reading from store.getters.getHideSharingActions

No other files need modification -> the store getter is auto-generated from the existing hideSharingActions key in settings.js.
