Subject: [PATCH] Add header change tracking to tab modification detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, changes to HTTP headers (adding, editing, or removing headers)
were not being tracked, causing tabs to not show the modified indicator (•)
when only header values changed.

Changes:
- Add 'changed' signal to HeaderRow widget that emits when key or value entries change
- Connect HeaderRow 'changed' signal to window's _on_request_changed handler
- Real-time tab modification tracking now includes all header edits

This completes the comprehensive change tracking system for tabs:
- URL changes ✓
- Method changes ✓
- Body changes ✓
- Syntax changes ✓
- Header changes ✓ (now fixed)
