NethVoice: TOPOS and SRTP options missing from trunks #8311

Steps to reproduce

1. Open the NethVoice advanced PBX interface.
2. Open Connectivity → Trunks and add or edit a PJSIP trunk.
3. Open PJSIP Settings → Advanced and find the Outbound Proxy field.

Expected behavior

The page provides the Disable TOPOS proxy header and Disable SRTP proxy header options, as in NethVoice 1.7.14. They allow configuring the topos=0 and isTrunk=1 headers for the trunk.

Actual behavior

The options are missing even though their rendering, storage and dialplan code remain present.

The current NethCTI GUI hook inserts the fields through an output-buffer callback. For normal and popover responses, FreePBX config.php first copies the unmodified HTML with ob_get_contents() and then discards the buffer with ob_end_clean(). The callback's replacement HTML is discarded, so neither control reaches the response. The previous regression test flushed the buffer instead of reproducing this capture-and-clean sequence and therefore passed incorrectly. A local reproduction of the actual sequence produces zero TOPOS and zero SRTP controls.

Components

NethVoice main, with FreePBX Core 17.0.18.54 and framework 17.0.33.2. Compared with NethVoice 1.7.14.

Suggested fix

Restore trunk page interception so the fields are inserted before the framework captures the response. Correct Core's $module_hook == moduleHook::create() typo to an assignment so the page can safely render in the interceptor's scope, and cover normal, popover and quiet responses in the regression.
