Grandstream: Hide BLF Remote Status And More Distinctive Ring
Hide the other connected party on the BLF of supported phones. When not hidden a busy BLF will show the other connected party/sttaus of the call by flashing back and forth between the BLF label and the caller ID.
It also impacts the park buttons, but they typically only show the word "park" because of the character limitations.
Also did more effective find/replace for the distnctive ring variables with regex! (plus a typo was made in the previous version)

Support enabling nway conference with Grandstream phones if nway_conference is set to true. If it is not true, it sets the conference URI back to blank to restore local conference
Grandstream template updates to support plantronics EHS via grandstream_headset_type and grandstream_headset_key_mode variables.
Also updated wallpaper and screensaver if/else statements to leave out the variables if they are not defined instead of clobbering the user setting. If you want to mandate a certain setting, just set the variable. If the variable is unset it will not overwrite on provision and allow the previous setting to remain.
Track whether or not a message was actually left in the voicemail box. Previously we only knew that voicemail answered, now we know whether the caller left a message.
Callers who didn't leave a message now show up in the "Cancelled" call filter in xml_cdr.php
Bonus: Fixed a bug with the originating_leg_uuid that was breaking extension summary from a previous commit and some other minor bugs/typos.
Excluded cc_side = agent calls from being marked as missed_call = true
Fixed the previous performance issue with adding the cc_side != 'agent' to the SQL and removed its filter from the rendering loop for the xml_cdr.
It is redundant to filter out LOSE_RACE when originating_leg_uuid is also filtered, there is an overlap where every call with LOSE_RACE also has an originating_leg.
For some unexplained reason, including the `"and cc_side != 'agent'` in the WHERE tanks the query performance from seconds to minutes on Postgres 9.4. It runs great on Postgresql 13. Reverting to the "blank content while writing the page content" approach for this value unless I can find the source of the problem. - Oh, also removed an unnecessary condition that prevents you from filtering by LOSE_RACE.
Same thing as in the xml_cdr.php page display. If the call is answered instantly, less than a second, then the difference is 0s, and the 0s is a visual indicator that the call was answered, it just took less than a second. Calls that didn't get answered have a large negative number stored in the TTA field, 0 is an answered call.
Re-implemented the commented out "Failed" call status SQL filter. It was no different than leaving the "Call status" search box empty. Removed the send_refuse restriction.
If the TTA is 0 because the call was answered in less than a second (so that the answer_epoch and start_epoch are in the same second), it would not display the TTA at all. This is safe to include 0 because "unanswered" calls are going to have a TTA that is is the negative value of the start time, significantly lower than 0.
