## Critical Bug Fixes
### Currency Display (£ vs $)
- Fix MenuBuilder.cs: Replace $ with £ for product prices (line 60) and order totals (line 329)
- Fix ProductCarouselService.cs: Replace $ with £ in product captions and multi-buy offers (lines 317, 325)
- Fix CallbackHandler.cs: Replace $ with £ in order confirmation message (line 800)
### Payment Amount Display Bug
- Fix MessageFormatter.cs: Remove flawed crypto detection logic (< 1.0m check)
- Bug: Order for £700 in ETH displayed as "£1.66" instead of "1.66 ETH"
- Root cause: RequiredAmount is always stored as crypto amount, not fiat
- Solution: Always display RequiredAmount with crypto symbol
- Impact: Fixes display for XMR, DOGE, LTC, and large ETH amounts
## Security: Remove PGP Encryption Feature
### Critical Security Issue Resolved
- PGP "encryption" was only Base64 encoding - NOT real encryption
- Shipping addresses stored as easily decoded text
- False sense of security for users
### Changes Made
- Mark EncryptWithPGP method as [Obsolete] in PrivacyService.cs
- Remove PGP encryption logic from order creation (LittleShopService.cs)
- Mark PGP properties as [Obsolete] in UserSession.cs models
- Disable EnablePGPEncryption feature flag in appsettings.json
- Add comments explaining feature removal
### Recommendation
Implement proper PGP encryption using BouncyCastle in future, or keep removed.
## Testing Required
- Verify all prices display with £ symbol
- Verify crypto payments show correct amount format (e.g., "1.66000000 ETH")
- Verify no PGP options appear in UI
- Test order creation without PGP encryption

**Issue**: Order creation failed because TOR proxy was being used for internal
Docker network API calls to littleshop-admin, causing DNS resolution failures.
**Root Cause**:
- All HTTP clients (BotManager, ActivityTracker, ProductCarousel) used
Socks5HttpHandler.Create() which checked Privacy:EnableTor globally
- TOR gateway can only proxy external traffic (to Telegram API)
- Internal Docker network calls to littleshop-admin failed through TOR
**Solution**:
- Updated BotManagerService to use Socks5HttpHandler.CreateDirect()
- Updated BotActivityTracker to use Socks5HttpHandler.CreateDirect()
- Updated ProductCarouselService to use Socks5HttpHandler.CreateDirect()
- TelegramBotService continues using TOR for external Telegram API
- LittleShop.Client respects LittleShop:UseTor = false setting
**Architecture**:
✅ External calls (Telegram API) → TOR for privacy
✅ Internal calls (LittleShop API) → Direct Docker network connection
**Testing**:
- Bot authenticated successfully with LittleShop API (200 OK)
- Telegram Bot API using TOR proxy (socks5://tor-gateway:9050)
- Container: 45eab050eeeca479680966b45742cf140cf7df0ed8e8ab5dc8c9e3e17739c88a

**Issue**: When users clicked "Browse Products" multiple times, Telegram API
rejected the edit request with "message is not modified" error, causing the
browse functionality to appear broken.
**Root Cause**: HandleBrowse method used EditMessageTextAsync directly, which
throws an exception when the message content is identical.
**Solution**:
- Replaced direct EditMessageTextAsync with SafeEditMessageAsync
- SafeEditMessageAsync catches ApiRequestException for "message is not modified"
- Silently handles duplicate edits without user-facing errors
**Testing**:
- Deployed to production (container: e1467c559ff6)
- Bot running as @Slukdevukbot with TOR enabled
- Categories API confirmed working (3 categories, 10 products)

Allows TOR proxy host to be configured via Privacy:TorSocksHost setting.
Defaults to 127.0.0.1 if not specified for backward compatibility.

MaxAutomaticRedirections cannot be set to 0 in .NET 9.0. When AllowAutoRedirect
is false, the MaxAutomaticRedirections property should not be set at all.
This fixes the TeleBot TOR proxy configuration crash.
