Added Trade History support for Exiled Traders 2.

What's new in 1.2.3:
- Added support for the new Trade History feature in the desktop app
- The extension can now proxy authenticated requests to the Path of Exile 2 trade history endpoint through your existing browser session
- Improved extension stability during background/offscreen reloads
- Minor reliability improvements for history refresh behavior

No new account setup is required. The extension still uses your existing pathofexile.com login session and keeps credentials inside the browser.

• Fixed background script suspension causing disconnects every 60 seconds

• Fixed popup briefly flashing "Not logged in" on open when already authenticated
• Security: network errors no longer incorrectly report authenticated state
