You are getting such error because of this code
self.onchange_stage_id(cr, uid, ids, vals.get('stage_id'), context=context)['value']
onchange_stage_id is not returning any dict having "value" as its key/item hence you got that error,
so you can handle it in 2 ways:
1. declare/initialize "value" in the return dict of the onchange function to ensure that it always returns "value" least dummy value.
Something like this
def onchange_stage_id...
res['value'] = {} # initialize res at the start of the function
2. Or you could rewrite your code like
x = self.onchange_stage_id(cr, uid, ids, vals.get('stage_id'), context=context)
onchange_stage_values = x.get('value', {})
x.get('value', {}), this syntax will first try to fetch the key "value" from the dictionary "x", if none found it will return second param i.e {}
I will check that.

FYI I think you may be missing browse wiith the stage_id to get the stage.
