Alerting: Fix rule API to accept 0 duration of field For (#50992)

Browse Source 
* make 'for' pointer to distinguish between missing field and 0
* set 'for' to -1 if the value is missing but not allow negative in the request + path -1 with the value from original rule
* update store validation to not allow negative 'for'
* update usages to use pointer
