Refine MeshCore repeater setup guidance

* Add a dedicated CT Mesh MQTT upload configuration page
* Link the resources page to the MQTT upload guide and MeshCore CLI command reference
* Add common repeater commands, MeshMapper, neighbor discovery, and Discord #test validation guidance
* Update the recommended flood advert interval to 47 hours

+    <p>These are the commands CT Mesh operators most commonly use while setting up or checking a repeater from the MeshCore command line. The full upstream reference is available in the <a href="https://docs.meshcore.io/cli_commands/" target="_blank">MeshCore CLI commands documentation</a>.</p>

     <h3 id="choose-site">Choose a Good Site</h3>
     <ul>
       <li>Choose a stable location with useful height, clear exposure, and enough sun to keep the battery healthy.</li>
       <li>If your radio site and panel site differ, remote panel placement is fine if it improves sun exposure.</li>
+      <li>Use <a href="https://bdl.meshmapper.net/" target="_blank">MeshMapper</a> to look for coverage gaps, likely line-of-sight paths, and candidate sites that would help the existing mesh.</li>
+      <li>Use MeshCore's neighbor discovery tools, including <strong>Discover Nearby Nodes</strong> in the app and the <code>neighbors</code> / <code>discover.neighbors</code> commands, to compare candidate locations before final mounting.</li>
+      <li>Before sealing the install, test the repeater at the planned location and confirm it can hear useful neighbors and can be heard by the main mesh.</li>
+      <li>If MQTT/Discord test monitoring is available, send a test message on a channel such as <code>#test</code> from the new repeater area. A Discord bot mirrors received mesh messages into the <a href="https://discord.com/channels/1359317424301801512/1484659122988126339" target="_blank">Discord #test channel</a>, which helps confirm whether the wider mesh can hear the repeater or companion nodes behind it.</li>

     <h3 id="tree-mounting">Tree Mounting</h3>
     <p>For tree installs, a common approach is to use a slingshot to place a lightweight mason line over a suitable branch, then use that line to pull up a stronger rope for hoisting and securing the node. Choose a healthy branch, avoid power lines, and make sure the enclosure and antenna can hang clear without rubbing through on bark or hardware.</p>
