Combat Phase only.
If one rule is (more) specific version of the general, then it overrides. Combat is generally during Combat Phase, Combat Intuition is a specific rule for combat when having/using that ability, so it overrides the general rule.
For Combat Intuition and TSEMP, both are specific rules, and neither is more specific than the other. Combat Intution is not a subset of TSEMP, and TSEMP is not a more specific type of Combat Intuition. In that case, all restrictions apply, and therefore TSEMP can’t be used outside of the Combat Phase.
