Network status indicator should only respect the latest / current request. Others finish in background. Replace stupid bools with an enum to track state. Be smarter about split requests.

+# Network Status Refactor - v2.6.1
+
+## Overview
+
+Completely rewrote the network status indicator system to use a simple enum-based approach instead of multiple boolean flags and complex timer management.
+
+## Key Changes
+
+### Before (Complex)
+- Multiple boolean flags: `_overpassHasIssues`, `_isWaitingForData`, `_isTimedOut`, etc.
+- Complex state reconciliation logic in `currentStatus` getter
+- Multiple independent timers that could conflict
+- Both foreground and background requests reporting status
+- Inconsistent state transitions
+
+### After (Brutalist)
+- Single enum: `NetworkRequestStatus` with 8 clear states
+- Simple `_setStatus()` method handles all transitions and timers
+- Only user-initiated requests report status (background requests ignored)
+- Clear state ownership and no conflicting updates
+
+## New Status States
+
+```dart
+enum NetworkRequestStatus {
+  idle,        // No active requests (default, no indicator shown)
+  loading,     // Initial request in progress
+  splitting,   // Request being split due to limits/timeouts  
+  success,     // Data loaded successfully (auto-clears in 2s)
+  timeout,     // Request timed out (auto-clears in 5s)
+  rateLimited, // API rate limited (auto-clears in 2min)
+  noData,      // No offline data available (auto-clears in 3s)
+  error,       // Other network errors (auto-clears in 5s)
+}
+```
+
+## Behavior Changes
+
+### Request Splitting
+- When a request needs to be split due to node limits or timeouts:
+  - Status transitions: `loading` → `splitting` → `success`
+  - Only the top-level (original) request manages status
+  - Sub-requests (quadrants) complete silently
+
+### Background vs User-Initiated Requests
+- **User-initiated**: Pan/zoom actions, manual refresh - report status
+- **Background**: Pre-fetch, cache warming - no status reporting
+- Only one user-initiated request per area allowed at a time
+
+### Error Handling
+- Rate limits: Clear red "Rate limited by server" with 2min timeout
+- Network errors: Clear red "Network error" with 5s timeout  
+- Timeouts: Orange "Request timed out" with 5s timeout
+- No data: Grey "No offline data" with 3s timeout
+
+## Files Modified
+
+### Core Implementation
+- `lib/services/network_status.dart` - Complete rewrite (100+ lines → 60 lines)
+- `lib/widgets/network_status_indicator.dart` - Updated to use new enum
+- `lib/services/node_data_manager.dart` - Simplified status reporting logic
+
+### Status Reporting Cleanup
+- `lib/services/map_data_submodules/nodes_from_osm_api.dart` - Removed independent status reporting
+
+### Localization
+- Added new strings to all language files:
+  - `networkStatus.rateLimited`
+  - `networkStatus.networkError`
+
+### Documentation
+- `assets/changelog.json` - Added v2.6.1 entry
+- `test/services/network_status_test.dart` - Basic unit tests
+
+## Testing Checklist
+
+### Basic Functionality
+- [ ] Initial app load shows no network indicator
+- [ ] Pan/zoom to new area shows "Loading surveillance data..."
+- [ ] Successful load shows "Surveillance data loaded" briefly (2s)
+- [ ] Switch to offline mode, then pan - should show no indicator (instant data)
+
+### Error States  
+- [ ] Poor network → should show "Network error" (red, 5s timeout)
+- [ ] Dense area that requires splitting → "Surveillance data slow" (orange)
+- [ ] Offline area with no surveillance data → "No offline data" (grey, 3s)
+
+### Background vs Foreground
+- [ ] Background requests (pre-fetch) should not affect indicator
+- [ ] Only user pan/zoom actions should trigger status updates
+- [ ] Multiple quick pan actions should not create conflicting status
+
+### Split Requests
+- [ ] In very dense areas (SF, NYC), splitting should work correctly
+- [ ] Status should transition: loading → splitting → success
+- [ ] All quadrants must complete before showing success
+
+### Mode Switches
+- [ ] Online → Offline: Any ongoing requests should not interfere
+- [ ] Production → Sandbox: Should work with new request logic
+- [ ] Manual refresh should reset and restart status properly
+
+## Potential Issues to Watch
+
+1. **Timer disposal**: Ensure timers are properly cancelled when app backgrounds
+2. **Rapid status changes**: Quick pan actions shouldn't create flicker
+3. **Split request coordination**: Verify all sub-requests complete properly
+4. **Offline mode integration**: Status should be silent for instant offline data
+
+## Code Quality Improvements
+
+- **Reduced complexity**: 8 enum states vs 5+ boolean combinations
+- **Single responsibility**: Each method does one clear thing
+- **Brutalist approach**: Simple, explicit, easy to understand
+- **Better debugging**: Clear state transitions with logging
+- **Fewer race conditions**: Single timer per status type
+
+This refactor dramatically simplifies the network status system while maintaining all existing functionality and improving reliability.
