Add Speak Player Dialogue setting

[RANGROO]

Summary

• add the Speak Player Dialogue global setting, enabled by default
• show the setting under Prompt & Rechat
• skip player-query TTS generation when the setting is disabled
• preserve player speech bubbles, dialogue events, and NPC response audio
• seed the setting for fresh installs and existing installs without overwriting user values

Validation

• php -l debug/db_updates.php
• php -l player_tts.php
• php -l ui/settings.php
• git diff --check
• database update applied with general_settings=202608050001
• disabled live endpoint probe returned player_dialogue_audio_disabled without creating an audio cache file
• enabled live endpoint probe returned a valid TTS hash and duration
• php tests/tts_pockettts_audiocpp_regression.php
• Global Settings page returned HTTP 200 and rendered the enabled checkbox in the Core section
• no new StobeServer or Apache errors were logged

The startup regression was not run because its safety guard correctly refused the live stobe database; that guard was not bypassed.

Deployment

Deployed locally to /var/www/html/StobeServer, ran database updates, and verified the background processor on port 12346. The setting was restored to On after the disabled probe.
