Remove triggers on label table

[lampajr]

Feature idea.

There are still some triggers on the label table that are related to the old label values recalculation mechanism that is no longer in use. Get rid of them.

Affected entities:

event_object_table	trigger_name	event_manipulation	action_statement	action_timing
label	lv_before_update	UPDATE	EXECUTE FUNCTION lv_before_label_update_func()	BEFORE
label	lv_after_update	UPDATE	EXECUTE FUNCTION lv_after_label_update_func()	AFTER
label	lv_after_update	INSERT	EXECUTE FUNCTION lv_after_label_update_func()	AFTER
label_recalc_queue	recalc_labels	INSERT	EXECUTE FUNCTION recalc_label_values()	AFTER

Describe the solution you'd like

Remove the aforementioned triggers and functions.

As part of this effort, ensure the above triggers and functions get removed.

We could also get rid of label_recalc_queue table as no longer used once all triggers (and functions) mentioned above are removed.
