refactor(logs): reorganize and polish controls toolbar layout

[vantoan1511]

Summary

Reorganizes and polishes the Logs view controls toolbar in LogsView.vue to make it more compact, readable, and compliant with Orbit's flat desktop design principles.

Changes

• Toolbar Structure: Replaced the previous single-row overflowing layout / <Card> wrapper with a structured two-row flat layout.
• Visual Design System Alignment:
  • Set variant="filled" on <Select> and <InputText> components.
  • Used <IconField> with <InputIcon> for search logs input.
  • Formatted resource selector labels with uppercase tracking (text-[10px] font-semibold tracking-wider text-muted-color uppercase).
  • Added a subtle vertical divider between stream actions (Play/Pause, Clear) and utility actions (Highlight Rules, Copy, Download, Fullscreen).
  • Applied uniform severity="secondary" variant="text" styling for icon action buttons.
