fix(site): implement agent logs improvements (#24455)

Polishes the agent logs panel in the workspace resources UI: consistent
padding, clearer behavior when switching log source tabs, and a more
usable download menu for long source lists.

- Use symmetric vertical padding on the logs container (`py-4` instead
of top-only padding).
- Add optional `showSourceIcons` on `AgentLogs` (defaults on);
`AgentRow` turns it off unless the **All** tab is active so filtered
tabs are not cluttered with redundant source icons.
- Anchor the download-logs dropdown below the trigger and cap menu
height to 6 items with scrolling so many sources do not overflow the
viewport.
