Reduce version polling frequency from 5s to 1h

[ramonsmits]

The environment and versions store was polling SC root endpoint, monitoring version, and platformupdate.particular.net every 5 seconds. These values are effectively static during a session, so hourly refresh is sufficient. This dramatically reduces noise in the browser devtools network tab.

Reviewer Checklist

• Components are broken down into sensible and maintainable sub-components.
• Styles are scoped to the component using it. If multiple components need to share CSS, then a .css file is created containing the shared CSS and imported into component scoped style sections.
• Naming is consistent with existing code, and adequately describes the component or function being introduced
• Only functions utilizing Vue state or lifecycle hooks are named as composables (i.e. starting with 'use');
• No module-level state is being introduced. If so, request the PR author to move the state to the corresponding Pinia store.
