feat: preserve sort/filter state across view refreshes

[Ppito]

Problem

When the auto-refresh triggers a view reload, the current sort order or/and active filters are lost. This forces the user to reapply them manually after each refresh cycle, which degrades the experience significantly when monitoring data over time.

Solution

Introduce an in-memory state that holds the active sort and filter parameters for the duration of the session. This state is initialized once and passed through (or stored at a scope that survives) the refresh loop, so each reload restores the view with the same sort/filter configuration the user had set.

Changes

• Added a ViewState struct to hold current sort field, sort direction, and active filters
• Wired the state into the refresh loop so it is read before rendering and preserved after each cycle
