TTEC vacuum: rearrange dps 1 to 3
- dp 1 labelled switch_go in Tuya docs. Seems this should be activate, not power.
- dp 2 labelled pause in Tuya docs. Assume this works in combination with dp 1 as push buttons doing the opposite thing - combine into activate attribute.
- dp 3 since dp 1 is no longer marked as the power dp, this can become the power
dp (it is marked as charge_go, which implies it controls power to the charging)
