Remove redundant map refresh calls and optimize refresh triggers

[Copilot]

After PR #160 implemented the Map Refresh Service as an always-on background service (5s timer + 25m movement triggers), redundant scheduleCoverageRefresh() calls remained in the TX ping flow, causing duplicate map refreshes. Additionally, the 5-second timer-based refresh was inefficient and not aligned with actual data updates.

Changes

Phase 1: Remove Redundant Map Refresh Calls

Removed redundant map refresh calls from:

• postApiInBackground() - Eliminated setTimeout wrapper with conditional refresh after API post
• postApiAndRefreshMap() - Eliminated setTimeout wrapper with conditional refresh after message queueing
• primeGpsOnce() - Eliminated conditional refresh after initial GPS acquisition

Before:

// TX ping completes → triggers immediate refresh
if (state.capturedPingCoords) {
  scheduleCoverageRefresh(lat, lon, MAP_REFRESH_DELAY_MS);
}

After:

// Map refresh is handled by the Map Refresh Service (25m movement or API flush)
// No manual refresh needed here

Phase 2: Optimize Map Refresh Triggers

Changed map refresh triggers from:

• ❌ 5-second timer (arbitrary polling)
• ✅ 25-meter movement

To:

• ✅ 25-meter movement (GPS-based)
• ✅ API flush completion (data-driven)

Implementation:

• Removed MAP_REFRESH_INTERVAL_MS constant and timer management
• Added checkAndRefreshMap('api_flush') trigger after successful API batch post
• Updated trigger types: 'initial' | 'gps' | 'api_flush'
• Simplified Map Refresh Service (no setInterval timer needed)

Benefits

• Eliminates duplicate refreshes in the TX ping lifecycle
• More efficient - map updates only when data is posted or user moves significantly
• Better UX - map shows latest coverage aligned with actual API data updates
• Simpler code - removed timer management complexity

Original prompt

Problem

After merging PR #160 (Phase 1: UI Refactor + RX Auto Mode + Always-On Services), the Map Refresh Service was implemented as an "always-on" background service that refreshes the coverage map based on:

• Timer trigger: Every 5 seconds (MAP_REFRESH_INTERVAL_MS = 5000)
• GPS trigger: When user moves 25 meters (MAP_REFRESH_DISTANCE_M = 25)

However, a redundant scheduleCoverageRefresh() call still exists in the sendPing() function in content/wardrive.js. This causes an immediate map refresh after every TX ping, which defeats the purpose of the background Map Refresh Service.

Current Behavior

After a TX ping completes, the following code triggers an immediate map refresh:

// In sendPing() function, after RX window completion:
if (state.capturedPingCoords) {
  const { lat, lon } = state.capturedPingCoords;
  debugLog(`[PING] Scheduling coverage map refresh for coordinates: lat=${lat.toFixed(5)}, lon=${lon.toFixed(5)}`);
  scheduleCoverageRefresh(lat, lon, MAP_REFRESH_DELAY_MS);
}

This results in duplicate map refreshes - one from the TX ping and one from the Map Refresh Service.

Expected Behavior

The Map Refresh Service should be the only mechanism for refreshing the coverage map. TX pings should not trigger map refreshes directly. The background service will handle map updates based on:

1. 5-second interval timer
2. 25-meter movement threshold

Fix Required

Remove the scheduleCoverageRefresh() call from the sendPing() function in content/wardrive.js. The block of code to remove should look like:

if (state.capturedPingCoords) {
  const { lat, lon } = state.capturedPingCoords;
  debugLog(`[PING] Scheduling coverage map refresh for coordinates: lat=${lat.toFixed(5)}, lon=${lon.toFixed(5)}`);
  scheduleCoverageRefresh(lat, lon, MAP_REFRESH_DELAY_MS);
}

Also remove the associated state.capturedPingCoords cleanup if it's no longer needed after this change.

Yes, the map still refreshes immediately on GPS fix during connection. The sequence is:

1. primeGpsOnce() waits for initial GPS fix and sets state.lastFix
2. startMapRefreshService() is called immediately after, which does an initial refresh using the GPS coordinates

The map will update just as quickly as before. The difference is the refresh now happens via the Map Refresh Service's initial refresh (line 934 in startMapRefreshService()) instead of inside primeGpsOnce() itself.

The Map Refresh Service continues to refresh the map every 5 seconds and when you move 25 meters, so the map stays current throughout your wardrive session.

Pull request overview

This PR optimizes the map refresh system by eliminating redundant refresh calls and replacing inefficient timer-based polling with event-driven triggers. The changes remove duplicate map refreshes that occurred during the TX ping lifecycle and replace a 5-second polling timer with targeted refresh triggers based on actual data updates (25m GPS movement and API flush completion).

Key Changes

• Removed redundant scheduleCoverageRefresh() calls from TX ping flow (postApiInBackground, postApiAndRefreshMap, primeGpsOnce)
• Eliminated 5-second timer-based map refresh in favor of GPS movement (25m) and API flush triggers
• Improved UI responsiveness by removing unnecessary setTimeout delays when unlocking ping controls
