fix: add dashboard asset filter panel with URL-persisted state

[Yusufolosun]

Closes #269

Summary

Adds a dashboard filter panel supporting asset multi-select, bridge filtering, status filtering, time range presets, saved filter presets, clear-all, URL-persisted state, and responsive accessible controls.

Root Cause

The dashboard page only implemented a local status dropdown and lacked the broader filter panel/state behavior required for narrowing dashboard data by asset, bridge, status, and time range.

Fix

• Added a dedicated dashboard filter hook with URL parsing/serialization and local preset persistence
• Added a new filter panel component under frontend/src/components/Filters
• Wired filter state into dashboard asset and bridge widget rendering
• Preserved existing widget customization and sorting behavior
• Documented filter behavior and URL parameter format

Testing

• ✅ Focused tests added and passing for filter parsing/serialization and time-range logic
• ✅ All changed files are error-free in editor diagnostics
