feat: add filter expression history with pinning for JSONPath/XPath responses

[pixel-hawk]

This PR implements a history management system for response filters (JSONPath and XPath) in Yaak, allowing users to reuse, and manage their filter expressions across requests.

🚀 What's New

Core Features

1. History Management
   • On Enter saves JSONPath and XPath filter expressions used in response viewers
   • Maintains a chronological history of filter queries per request
   • Deduplicates entries to keep only the most recent occurrence
   • Clean the filter history when requests are deleted
   • Input sanitization (trims whitespace, ignores empty values)
   • Toast notifications for user actions

---

2. History Dropdown UI
   • New dropdown component accessible via history icon with count badge
   • Groups history items by time: Today, Yesterday, and Older
   • Visual indication of currently active filter
   • Individual delete buttons for each history entry
   • "Clear All History" action for bulk cleanup
   • Truncates long expressions (80 chars) with full text on hover

---

3. Pin Functionality

• Pin frequently-used filters to prevent them from being removed
• Pinned items are excluded from FIFO cleanup when history limit is reached
• Pinned filters appear in a dedicated "Pinned" section at the top of the dropdown
• Pinned status persists when re-entering the same filter expression

---

4. Configurable History Limits
   • New workspace setting: "Max Filter History" (default: 20 items)
   • Configurable range: 10-200 items
   • Accessible via Settings → General
   • Database migration to persist setting
