/**
 * P25 reflector link/unlink form (admin-only).
 *
 * Loaded inline by /index.php only on the admin path
 * (`$_SERVER["PHP_SELF"] == "/admin/index.php"` gate).
 *
 * Form fields:
 *   p25LinkHost  — talkgroup number (numeric, validated)
 *   Link         — LINK or UNLINK (UNLINK targets TG 9999, the P25
 *                  parrot/disconnect TG, distinct from NXDN's literal
 *                  "unlink" target)
 *
 * On submit, runs `sudo /usr/local/bin/RemoteCommand <port> TalkGroup
 * <target|9999>` against the P25Gateway remote-control port configured
 * in /etc/p25gateway. Triggers a 2 s `setTimeout` reload.
 *
 * Inputs:
 *   /etc/p25gateway                       Gateway config + remote port.
 *   /usr/local/etc/P25Hosts.txt           Operator picklist.
 *   /usr/local/etc/P25HostsLocal.txt      Local additions (optional).
 *
 * NOTE for the security pass: validation is whitelist-regex; no
 * setEmbeddableSecurityHeaders() call in this file. Coverage gap.
